I don't hold any hope for a fix as if you have a look at the sheer number of stats available it would be a mammoth task to rebalance (not that its balanced now). People with whinge and moan about WAR and Mythic was better at balance than this, makes me wonder if any of them still work for Bioware.
If your 100% PVP oriented just roll a sorc/operative and be done with it
This from a BH PT tank who recently learned that hes not a tank at all and he might as well be an enduranced stacked cloth character.
edit: Why oh WHY do devs think that adding tons of different types of stats makes the game better? Probably just to keep us on the loot treadmill longer.... tank set, pvp set, healing set, resists set,crit set....
edit2: As a PvE first and foremost game don't expect much. For crying out loud just look at the low number of pvp maps!
