Ok I got back into Swtor lke a month ago, been coming back on and off for years.
I disagree with super high bolster, mostly for the reason someone else mentioned that it is a big problem with min/maxing lesser gear for best result, but also because games like gw2 isn't really fun. Gear progression is part of the fun, as long as the gap isn't too large.
Pvp/warzonxes has it's balance problems, but it's not too bad, certainly less than in the mmo I most recently got fed up with!
My best advice, make small changes. Big changes may totally wreck the game. Removing pvp specific gear was close, but I find that compared to this other game, swtor isn't too bad!
