I use Vegeta all the time.
He's not very strong in the current version, compared to Cell, Trunks and Gohan (with his ridiculously low transformation level)... but I like Vegeta.
I like to use him because noone else uses him. His hitpoints are ok, his attacks are kinda uninteresting, and his speed is ok. He's just an average character, IMO. Also, his Transformation level is a little high, at 2-million which is really tough to get (granted, I'm not that great of a player yet).
The biggest problem I find with Vegeta, is when I use his beam attack... he gets this power-aura on him, and I can't f***ing see where my crosshair is pointing because his aura is too big
I want to start to get good with Krillin too, just cuz he's a cool short, bald, monk that noone else seems to play.
