I hope this doesn't sound too much like a complaint, I'm just trying to understand as I can't see the reasoning behind it. It seems to be becoming more and more common for tanks to pull, for example, 2 groups of trash, dps begin to burn them down, then the tank runs to the next group before all enemies have been dealt with. Quite often during this, buffs and procs are falling off and it's amazing how often I've seen the tank even run into locked doors that won't open until all trash has been cleaned. I guess my question here is why? Is there a advantage to this? A dps gain I'm not seeing?
