My war can handle the same amount as my pld. The clear time of both with an appropriate setup (war/brd/drg/whm - PLD/BLM/BRD/WHM). There are no problems in either setup, war just takes more effort to play, and requires more skill to execute. In fact, the Tonberry King is easier with a war.

That said, I'm not arguing that WAR is fine in other content.
