Ground Blast is incredibly flawed. It's not even worth it's godlike Meter Burn because if your opponent doges it you're left wide open.
I completely disagree. It's not as good in zoning as Black Adam's low lightning, since it doesn't track and has a long animation if it whiffs, but it's +15 on block and with 4 different ranges you can throw it at, it's going to be a staple part of Zod's zoning.
I think with time and work, Zod will be just below top tier (Batman, Superman, Aquaman, Black Adam). He's going to favour set ups and intelligent play. His trait works like Batman's crossed with Sinestro's, and that alone makes his potential very high. If B2 were an overhead and Wrait could attack quicker on summon, he'd be set.
