Lower Hero Regeneration times.
Let's start by saying im still not much of a fan of this update, bring a new th10 SUCKS
but if the game is going to stay this way, you better adjust hero times cause you absolutely need them to attack bases for storages. Even boosted im stuck wasting my barrack boost, cause my heroes are still 10 minutes behind once they die completely. Over an hour is just stupid.
Boosting barracks is is the only way to make ground now, and this is making me waste gems.... But I guess that's what you wanted, right supercell?
