I donīt have to remind you how long a DPS usually waits until the flashpoint actually starts using groupfinder, and to be dissapointed after that long time over and over again is what I call gamebreaking.
You're being doubly selfish. You want people to take more time on runs, and enjoy it less, so that yuu can enjoy it more. And you play a DPS. DPS don't get a vote on anything. Supply exceeds demand, and so DPS have no value, and therefore what you want carries no weight. If you want to choose how a FP is run, play a tank or healer. Those two roles have a say.
