Warrior doesn't raise stats of mobs... It takes longer because its 3 DPS instead of 4. Which means 3 rogues/mages are doing the job of as if there were 4, while the warrior tanks. I don't see why people try to bring warriors down as a class. If you don't like warriors in parties, no need to run with them, or just complain to sts, and they'll discuss about buffing warriors in a couple of years.
