Oh I too have experinced this... I took my geared lvl 55 Assassin to Black Hole to do Torvix on Monday and loved it, then returned yesterday and almost died in EVERY fight... Yes I set my skills, checked my armor rating, had my buffs, and a stim but still my lvl 55 character was getting owned by lvl 50 NPCs... pathetic... couple that with the other Hutt-sized failures of this update and the result... I am taking my subsciption to a game that might be fun to play... so long SWTOR and Bioware!!!
