Who to use generic 4* gem on?
So I bought the 4* awakening gem offer a little while back and was going to save the gem in case OG vision offers came up again, but I've pretty much given up on that now. I'm really debating between Doctor Voodoo, Wolverine, and Vision AOU. I could also put about 20 sig levels in. I'm willing to hold it for anyone better as well. I'd appreciate any advice from people who have all of them awakened.
