Here is what killed wow and why I like SWTOR better.
Gear score, dps meters, mods and faceroll dungeons / raids attracted teenagers, and unfortunately many of them were trolls or emokids, as I prefer to call them.
If you lacked one point in Gear score, you were excluded from everything. This led to endless grinding of materials with ridicoulous low drop rates and in the end, I stopped.
So for my sake, keep the game as it is in this regard and lets all have fun. I dont care who does most dps or heals or best tanking. I care if we get the boss down or not. If we dont, analyze, guide and suggest to people how to improve. That is what is needed. Not to shove dps meters, bad gear score down our throats. It is all but educational and it is certainly anything but motivating for any player.
