All of these changes are very welcome. I agree with all of them, but some I don’t think are “enough”.
The trollhammer needs a redesign to he honest. It’ll still be too good on Engi, and it’s still too good on IB. But nerfing it to be ok on Engi will likely kill it on IB. Making something as powerful as an career ability but ammo based just causes problems.
Bomb generation needs to have a longer cooldown based on difficulty. Cata should be 160s, Legend 120s.
