But I mean, look at it:
Tidus - Fast, nimble
Wakka - Aerial
Lulu - Elemental, magical
Auron - Armoured
None of the other enemy types have strengths that Kimahri, Yuna or Rikku are designed for. Sure, I typically send Kimahri to bro out with Auron and Rikku plays with Tidus, but neither of them does it as well as the dedicated. It's almost not worth the effort. Abusing the game to make Rikku and Tidus super quick is the only way Rikku even becomes useful.
