Don't get me wrong either...you may not believe it but I am not a scrub, I know I can play. i can heal a speed run quite well, as a matter of fact when playing with good players I get compliments for making it faster. Running off, without a pause, never considering the MP or TP of your group members causing wipes makes the run go SLOWER. A pause here and there, some situational awareness to realize that your group is spread chasing is not optimal for what you are trying to acomplish, click of a regen if before you start pulling again if you can't wait 5 seconds because all the mobs will be on me if you don't.
Besides that, we are real people, why can't we just say hello to one another and communicate for 30 secs? Why do people have sprint off the moment they can?
