There is a discord channel for the game and they are actually listening to most of the suggestions there.
Approximate changes were:
1) Skip quest button - puts your quest wait time into 24 hours immediately but no reward.
2) Cooldown fixes
3) The biggest bad thing is that building times are insanely long now... They were too short, I agree... but the current ones are just way too much.
4) Skill cost reduced by a lot, especially at higher levels.
5) Daily rewards - new 14 day hero. They still didn't seem to fix the 28 day hero reward, but they promise to do at least something about it(maybe some small compensation, but probably not the hero you are supposed to get)
