Okay this may just be my opinion but I honestly believe that all the characters are fine, sure a spamming raiden, kratos, sackboy & drake **bleep** me off but with good evades & technique it's fine.
Sackboy was good before it was that his lvl3 lasted too dang long Raiden lvl1 should be a quick spin kick not several. His lvl2 is better than half the casts' lvl3s; ap generation is fine just shorten that lvl2 down. Heihachi lvl2 last too long too.
I think that a lvl1/2 should NOT be able to get more kills if the screen is cleared that should only be reserved for the ones that actually save up for a lvl 3
What do you guys think? I hate the complaining about op & nerf stuff let spammers be & ap generation; it's the supers that do the killing.
