Well... The problem is everyone complained about the speed runs in AK so much that they decided to not only to break the exploit but to increase the amount of trash pulls. Making it much slower to gain tomes, and making CM - a story dungeon the fastest possible way to farm Philo. So instead of complaining about the speed runners ask why did SE make it this way. Not only that AK was only a 4 man which allowed those of us to create a group for speed running much easier.

Besides that point I typically take a group of 4 with me to CM to speed run and we will run it and leave anyone behind without complaining or raging or even saying anything to them at all. If they want to watch cut scenes fine, just don't complain when your locked out of a fight or you miss cut scenes because your still watching another when we pop the next cut scene.

BTW as a Tank its your choice if you want to speed run or not. Unless your off tanking then your pretty much just a DPS in CM.
