PLD = Easy to play. Mitigation class. Typical sword and board MMO tank.

WAR = Takes a bit more to play, more skills. Self heals instead of the PLD mitigation. More fun in general, not cookie cutter in coil though. Getting a buff in 2.1. They also deal fairly acceptable damage when their buffs are active. It's also alot about learning when to use which skill to get the most out of the next.
