killer frost is the only character with a safe invincible wake up. have none of this, safe/fast wake ups shouldn't be invincible, invincible wake ups shouldn't be safe, etc
More characters with less humans that aren't super powered. I'll be happy with these characters
HEROES: Blue Beetle, Dr. Fate, Static
Villains: Scarecrow(!!), Darkseid, Atrocitus, Larfleeze
For the last casual thing MORE VISUAL APPEAL. This goes for stages, designs, and MOVES OH GOD THE MOVES. Why are the Lanterns some of the most visually unappealing characters when they have unlimited potential with constructs? Why do we have clone stages of day/night and not fucking Apokolips or Oa? Why does the game feel so rigid for some characters?
As far as the game itself goes, it needs better walk speeds. Like, I'm not even kidding it's so obnoxious when I walk like a slug and Wonder Woman gets to iaDG in my face. There shouldn't be an acceleration; that's my biggest gripe. Generally I'd say small walk speed improvements after that, but selectively.
