    I don't think it is even remotely as easy as you think.

    If a healer is posted behind a group of troops that you want to protect, she heals them back to full health often if they are going against low damage splash. If they are against high damage single target defense, one dies anyway.

    If the healer ignored full health troops, she would heal the group, then try to cross the map to the next group. We all know she would never make it. You would get a healer that will only help you if you deploy all troops from one spot. The only people who attack like that think that programming AI changes is easy.

    It doesnt seem right that healers should go for one or two heroes where the healing effect is dampened, rather than towards the 14-16 giants

    When I read the idea I thought of healer flying over the town hall throwing heals all around the map.....it was beautiful

    It WAS working like that. SC CHANGED it when they IMPLEMENT "healers' FIXED" a couple of update ago. They don't want healer to switch target anymore. They make healer sticks with one group. How do they do that? They make the trigger radius smaller, so healers only recognized the closest group of troops nears them. It stinks.

    There are bases that allow you to deploy WBs and other troops to flank for her and can take out A/Defs, which will allow her to stay alive longer than any heal spell will. she could last the entire raid this way. no heal spell will last the entire raid, or follow the troops around healing them. the few seconds the heal spells do last must be critically placed and timed. now that the SAMs don't insta-KO her, she is a much more viable troop for support of Giant variant armies, or the Healer-Royal combo I have seen deployed, heck even Barch just got more interesting IMO!

    Has anyone else experienced as I have a lost a bit of confidence in them. I had though that the healers AI had been revamped and this shouldn't have happened. Am I wrong?
    So, the healer is still working as intended, then.

    There's you problem. You are holding back the healer too long. By the time you deploy the healer there's a whole bunch of distractions for her. Deploy giants then deploy healers. With only giants around the healer will have no choice but to lock onto the giants.

    The AI is designed to stop healing those troops with full health. But it is also designed to stop healers from going across the map to chase a damaged target instead.

    The only have a radius of 6~7 tiles on which they "see" other troops. If troops are not within that radius, then healer will just ignore them.

    They've had a preference for heroes for a long time now. Probably since last healer AI fix. Healer preference works based on troop housing space, with BK having stronger preference than a PEKKA at least (but less than two pekkas).

    To keep healer's attention over BK will require 8~10 giants. But if the giants split into two groups of 4~5 then healer will prefer the BK anyway. The troops needs to be very close in order to be considered a group by a healer (like within 1 or 2 tiles distance).

    Solution would be to deploy heroes later, or maybe use tank troops with higher housing space.

    No way. That's how it worked before and it was horrible. Now one can make the healer lock onto a single group and stick to it, if you know what you are doing (see above). But with the old behavior the healer would switch back and forth between troops, probably getting herself killed, or letting troops which she is supposed to be healing get killed, due to intermittent healing.

    See above. If the giants were too far away then healer will just ignore them, even if there were a group of 1000 giants.

    Also, even if there's 14~16 giants in a "group" it doesn't mean the game AI sees them as a single group. Maybe they were not close enough and were split into three groups 4~5 troops, and as I mentioned 5 giants might not enough to pull healers of a heroe. Do note that the if the heroe is full HP and has not taken any damage recently the healer should switch over to heal the giants (if they are close enough).

    I don't really like this idea much. So healer heals 5 targets. Which 5 targets it should heal? How can healer AI pick the "correct" targets to heal? Right now it heals everything in the AoE. As long as it targets the right group she works great. But multi-target healing she might just heal the "wrong" 5 targets and ignore the one target that should be healed.

    No it is perfect once you understand and adjust your deployment accordingly. Besides, healers do switch targets.

    As mentioned above if the target group goes to full HP and stops taking damage for a few seconds the healer will happily switch to a different group which is taking damage. If two groups are taking damage, then the group with the higher combined housing space will attract the healer more, possibly causing her to switch targets.

    IMO, SC did a great job with healer's AI. It is difficult (or even impossible) to make an AI that will satisfy the needs of every single player. The current AI is quite manageable when one fully understands how it actually works.

    I used healers since I was TH6. I used it to farm all lego wall and Heroes to 25. I know how Healers work. They do switch targets, I agree. I never said they don't. SC is the one who claim that they would stick with one group when they implement the "healers AI" fixed. But all they did is make the trigger radius of healer smaller. As the result, they don't recognized other group of troops so they don't switch (fly back and forth and could not decide which one to heal)

    "✔ Healers have been trained to avoid distraction: now they will always try to stick with and protect the same group of friendly troops"

    I have some video prove how stupid healers are. Watch the whole video because there are multiple places.


    In the video above, healers go straight to heals Queen and archer. and it would sticks with it forever. It doesn't go for Giants even though the Queen and Archer is fully heal. It only move to the group of Giants when it get close to them. See? It's not that it doesn't switch targets as they claim, they make their trigger radius SMALLER.

    Next, https://www.youtube.com/watch?v=JyBi7o2gRJA

    Healer seem focus on Queen when they are around. Yes, it does switch back and forth between Giants and Queen, but it looks like it focus more on Queen. Queen was shot by mortar, but mortar shot every 5 second. So the Queen is healed quickly. They should move the group of giants who is shot down fast. But no, they even moved from the group of giants to the queen whenever the queen take damage.

    Next,

    This one it's clearly that Healers priority healing queen. Why the heck do you leave a group of giants who is being shot down to fly over to the queen?

    And this one is funny, actually:

    You can see that healer is priority Queen, as usual, but the next very funny thing is the King's banging the Queen, and the Queen standing still so he can bang her.

    Don't get me wrong, I love giants healers. And I do well with them. But sometime, they move unpredictable, and it ruin my raid because I expect them to do something differently. Sure, I can adapt, but it doesn't mean it should not be fix. They (SC) should not touch Healers AI at the first place. It was worst, way worst after that update I quote above.
