I tend to play with Vegeta a lot. While it's true that his trans is late, it's also an incredible one, providing him some of the best attacks in the game. And you're forgetting the impact his quicker animations make. With vegeta, your simple melee hits hit quicker, and your blocks are quicker. Overall, Vegeta just seems to react quicker and handle smoother than most characters. And his gallit gun is still quite a potent beam, you just have to use it with focused power, unlike the big radius blasts he gains post trans. The only problems I find with his gallit gun is the glowing disc, and his renzoku could probably use some work. While granted, another attack wouldn't be bad, it isn't necessary, as he's still quite a potent character in the right hands.
