Making Healer relevant for th8+

The healer is a great hero concept but it is pretty irrelevant in war and even outside of war for th8+. Now that the lower bases have an extra air defense, it's usage is really going to plummet. I think this simple change might be in the right direction in terms of making the Healer relevant again.

All deployed healers now have a toggle ability by clicking on the unit portrait. When clicked, every healer will go from flying mode to walking mode. When walking, Healers use their wings as a shield, adding additional HP. Healers walk more slowly than they fly but no longer take damage from air attacking units. While walking, Healers cannot heal other units (but as an idea possibly they could slowly heal themselves).

Executive Summary:

• Healers have a new ability to land (all deployed healers land when portrait clicked)
• While landed, healers walk at a slow pace
• While landed, healers cannot heal other units
• While landed, healers do not get targeted by air attacking units
• While landed, healers max HP increases slightly
• Bonus: While landed, healers heal themselves for a small amount
  

I really think this idea will add a new dynamic to healers and the game as a whole. Now healers can be deployed early on but then landed when coming in range of air defenses, only later flown again to resume healing troops. By making the healers walk when landed, they stay in possible danger of bombs and other defenses but they also will better stay with the army. Making their walking speed slow will prevent them from being too overpowered, however, because they will usually be out of range to heal when flown again. Adding the addition HP in landed mode will help compensate for the additional ground threats.

The goal is not to make the Healer overpowered, but to get them back into the game. Currently, th9+ only use healers on their Queen to do snipe raids. This mechanic makes the Healer a gimmicky unit right now.

The healer has always been a support troop, but she still has her use at TH9+. Attacks at this level become increasingly complex though, which means that using healers becomes increasingly tricky. If using on units other than the Queen, you have to either take out the air d first, or rage through the air d and/or heal the healers so your troops take the air d out before the healers die. And then of course at TH10 there's infernos to consider.

In any case, this is an interesting concept, though I think the toggle needs to happen in the army camp not during battle, but my initial reaction is that it would probably make healers OP, at least for TH9 and below.

I think playing with the numbers could eliminate any over powered effects and also changing at what healer level this ability becomes available.

One big way to make it so it isn't over powered would be to add a delay in flying and landing and during this time the healer cannot heal. If it takes a few seconds to land or fly then clicking the portrait would really be a critical decision.

I think having more variability to the attacks, where it takes players doing things at the right time will make it so higher skilled attacks are possible. No more it is just deploying your troops in the right order, but now during battle you need to make snap decisions (like with the Hero units).
