I don't care to make a wall of text essay on the matter, others did it already I just want to join the choir and figured this is the best way to be head since I'm subscribed why the hell not, right?
It's bad, it didn't make the game more challenging it just made heroics grindier and more time consuming. Not a lot of extra time, granted but enough that I feel it's an overnerf. The HP nerf was massive across the board, the DPS was enough that companions can't take down an NPC pack without dying anymore and the only thing that was overtuned was the healing anyway and that needed a slight surgical nerf not a bat to the head. I'm unhappy with this change as are many many others.
