What he said... Moreover, when you ditch the tank, you open space for... another Mage or DPS. So then you have the possibility of 2 pet tanks, plus off-tanks via Servants. People can shout to high heavens about how great warriors are, and they are, fantastic tanks. But Your warrior is going to need a Slower/offhealer to really take on the stuff a mage earth pet cant, which, as I said, makes your groups DPS abysmal. You'll need 2 DPS mercs just to get along and that makes the experience atrocious, too. A Tank-based box team probably puts out 100k DPS sustained ( no mercs ) > 30 minutes. My 3 Mage box team is going to break 300kdps ( no mercs ), and its also easier & I think funner to play. Is a warrior/slower combo better than a Mage pet? Hands down, yes. Is it better than 3 Mage pets supplemented by Servants? Questionable, sometimes yes sometimes no. The Tank-based group can do things I cant. I can also do things they cant because of the vastly superior DPS. It is ultimately a matter of preference & playstyle.
