Right, but Auron has some crippling weaknesses of being slow as fuck and having low Evade and Accuracy. This isn't a big deal at the beginning where everything Auron can hit dies before its a problem, but it loses its luster later on when shit can actually take what he dishes out and return it in spades, especially on the magical front, which is MDef is kinda wack. He's fucking awesome as a character, but in gameplay he has some weaknesses.
Statistically, Wakka isn't that different from Auron, except his Accuracy is magnificent and his status effects are invaluable in this game.
The only real big difference in strength between Wakka and Auron is that Auron can Pierce, and if it wasn't for that, you'd see very close damage between the two from the jump. Wakka can't Pierce, so most players think he's much weaker. But guess who else can do Piercing damage with his weapons? Hell yeah, dawg. Sending Kimmi down Wakka's path did a lot of favors for him.
