Killer Frost needs more recovery on slide immediately.
Black Adam doesn't need to be hit that much, but I agree with the lightning meter gain. Otherwise, he's been normalized well and his combos don't do all that much damage comparatively.
I despise Scorpion, but if he's going to be here, he needs to be usable. Really small dmg boost and some adjustments to his specials to make them slightly more safe again.
Some of Grundy's armor needs to be taken away. Played properly, it's impossible to keep him out.
Normalize Bane's trait, slightly less damage and definitely less penalties with Venom down.
Lex needs quicker start up on pod lasers and leave mine alone, but it should stay active longer. Otherwise I think he's fine.
Love the Superman suggestions across the board. Don't decrease damage, but increase scaling and eye zap recovery. F2,3 need a reduction in range and ability to hit aerial opponents. Slight increase to breath recovery is needed as well. He'll still be top tier easy.
I think Shazam's command throws should do a bit more damage, but that could be rectified with the ability to cancel into his trait. I mean, they do rely on meter to be remotely effective anyway. His teleport should have more invincibility on startup as well.
I think Sinestro's back 1,3 is fine, but the fixes to meteor are sorely needed. Maybe a little less scaling? He's pretty balanced IMO.
Slight increase to Zod's strings. As it is, he's pretty unsafe. Definitely fix all the glitches asap.
REPLACE ZATANNA WITH ATROCITUS K?!
