Usefulness!

[Angel_from_hell]

This is my first time playing FF12 and I am not the best in planing tactics, and I am to lazy to level all of the characthers so I just stick to my dream team.
Vaan
Balthier
Fran
But I think that next time I play the game I am surley going to level all of the characthers so all of them is at the same level.

I'd like to use them all but I'm just too lazy. I pick 3 and everybody else gets screwed. I've played the game 3 times now (I'm a freak like that), so I've used a nice mix and match of them all, but my favorite team is Vaan, Ashe, and Balthier simply because I like those three characters the best personality wise.

yep same! (apart from playing the game 3 times)

I just played with three people of my choice. I shouldn't be forced to spend time leveling every character up. Well, thankfully they gain LP even when they aren't being used, so I can use them as Quickening catalysts.

I have a boys and a girls team. It just worked out this way: Basch my tank, Balthier as my archer and Vaan as my thief and Ashe my female tank, Fran the archer and Penelo the thief.

Oh and Team A uses magick while the girls use techniques. This way I always have MP for quickenings
