So, I just watched a YouTuber showcasing a few raids in higher-level gameplay where the attacker failed - he ended up at ~45~49 %. Let's say I'm at 49%, and I only need one more building to get the one-star, but there are no 'free' buildings left. Then I have to remember which buildings I already have damaged, so that my small amount of troops, preferrably, are able to take out the building with the least amount of health.
Now, to not have to remember each buildings health, I suggest that SC add a feature that makes it available to see each building's health during the whole raid, just as in Boom - and not so it disappears after a few seconds like it does today
