I totally agree.
The thing that is bothering me is they are sending confusing messages on what is the idea behind the changes. If you read the release notes, it says:
And after that, they removed bomb mining from the game, at least the way people use to do it. So, one thing is trying to balance the game, and a totally different thing is changing the way you are use to play.
I felt the same with the powercoil change. These changes are not balancing are gameplay style changes, so devs please, we are not in alpha anymore, try to keep the surprises only for new features.
Thanks
