I'm in the same boat as you.Tutorials are wack but fukk it, its not guilty gear deep so we gonna figure some shyt out.
Cell and 16, hit definitely top tier Goku Black looks promising too, yamcha too
Cell, is just straight up fukking nice. He's got tools for everything. Zoning, rushdown, setups, solid assist. Dude may as well be DBZF's Dante. I can't see a situation where 3 months from now people look at Cell on a team and laugh.
Meanwhile Nappa.... I was fukking around between training and story mode with him (because this shyt is legit entertainment for any DB fan) and I'm just not feeling it. He's a big boy with big boy damage, but it feels like everything with him is all or nothing. I don't know what he's supposed to do better than 16.
Ginyu is the game's Dan someone beats you with this dude just log off and report them. Dude's sole purpose in the game is to let scrubs charge a Level 7 Gohan then steal it and proceed to make a highlight reel for a youtube montage
