In a game that lets one character play every class, I have absolutely ZERO problems with them making certain classes blatantly better for certain fights. I'd prefer it, it would separate the dedicated from the less; opening up more room to move in designing fights. This would only apply to top-tier encounters though, who cares about tanking a dungeon boss skill, they're not even a remote challenge.

If this game was like a traditional MMO in the sense of being locked into your class then it's bad design.

The problem right now however, is that in end-game content PLD>WAR for MOST - if not all - BC fights (minus maybe T4 adds).

My 2cents.
