Don't go back to cap 54 skill tree, it's gonna be a bullshit because u won't be able to just revert without consequences, regardless the fact if u gonna keep the new skills or not. It gonna cause a lot of issues and bugs and u all will end up working ad reworking for atleast 1 year.
Currently after last skill change patch there were a lot of ups and downs, however, these over the time have been worked on and a lot have also been fixed, you now are going to revert all and to undo all ur effort and work, We have imo reached a good point atm despite the present issues which are way less than what we gonna have if a revert happens, because u gonna try to keep some changes, because yes, u change 1 thing in this game and it bugs other things at same time without wanting, so why to not rather tweak what we have now becasue we are know all the issues with it because everyone is familiar to the current situation? reworking all means another way to find a solution, ppl think that gonna solve the issues, it won't. It instead gonna work opposite.
