Cheer after combat when no enemy units are in range
Cheering as is done now is highly unfair and illogical. Cheering units are immune to all damage for 2.8 seconds.
That means unit A attacking cheering unit B is wasting its attack and doing 0 damage while taking damage from anyone attacking it (unit A).
That can save cheering unit with 1 HP from being killed what is not fair to the attacker.
removing immunity to damage while cheering
do not forcing cheering order so unit can respond to attacks
removing cheering from promotion
cheering after unit cannot find more targets(units) while in combat and has nothing else to do
tell units around to cheer as well
