DPS Counters, "optimal rotations", and other min-maxing will do nothing but pull you out of the experience that Bioware has so painstakingly designed. It destroys immersion, and irritates those who may not be the most experienced MMO players.
Being measured and graded based on which skill tree you chose, or the pace at which you decide to play the game turns a role playing game into a mindless button masher. To make the inevitable comparison: World of Warcraft became progressively less fun with every new statistical addon (Recount, Gearscore, etc)
