I trust them, they are all good developers put together by Sony. Clockwork is even one of the best mvc 2 players in the world, so they know a thing about fighting games. If you don't trust them that's fine but I'm just saying I do. They have months to balance the characters
I completely trust SuperBot to make this game great.. I have the beta and so far the gameplay is amazing.. so when it releases it should be a great game.
The people who are the easiest to combo with should all be getting the lowest amount of AP per hit, since they can keep it going much easier and without having to groundbounce or wallbounce most of the time.
Just look at the video where Omar explains a lot about Raiden. His combos are super easy and super long.
Also on the sweet tooth thing his level 1 is most likely only 1 kill
I main sweet tooth in the beta he gains alot of ap if you combo.. ive gotten a level one in 8 seconds before...
but his level one normally doesn't kill more then one person.. ive killed two people at once a few times but its hard.
so he's kinda a bad example of someone who could be considered OP
