Wakka is super bad ass now. I usually kind of stop using him after a certain point in the game. I mean he's useful enough and all, but I always end up using Auron, Lulu, and Tidus as my damage dealing trio. This time I bothered giving Wakka a bad ass weapon and boosted his strength a bit. Now his strength stat is even with Auron's, but Wakka has superior agility and evasion! Definitely a better partner to Tidus's abilities.
