I agree that I am still having fun, maybe even more. But... there were some power sets (invun in perticular) that were not balanced, they were out-right nerfed. FF are completely worthless compared to sonic, not that its not a valueable power but in comparison to sonics, sound is just better ff's. As an invun tanker I feel like an invun scrapper without critical. But I hope that when you say your working on the def problems you really are. Im not demanding or even asking for an I4 rollback. To be honest tanks, especially invun ones, were a little boring to play and to play along side. I dont really know what I want you guys to do, but there has to be a "balance". I just hope that being the game developers you find the right place for most sets and powers.
