Man don't make the same mistake I did and invest in jc becuz he's a black guy with a goatee, hood, and glowstick.
Bruh I stopped farming jc at 5* g7 and thank God. That guy was useless. He did nothing that another toon couldn't do better. He is like lumi's random mixed son. She is just better in everyway. Couple months ago I remember he was recommended over her at times because his cool down is shorter. LOL SO? He hits like a wimp, heals like a wimp, and w/e his useless other ability does. Oh yeah he throws some water and it hits like a wimp. Don't give this guy a chance,drop him like a bad habit. Farm his dad mace he's better and that's sad (yeah, mace+lumi=jc...obviously right?)
On the other hand I don't have Barris atm, but I have fought alot of her. She is just better than jc. If you want a healer she does that we'll, but that's it. Don't even look when she does her basic because honestly I think she might do negative damage. I always wonder how long it'd take for her basic to KO 5s or savage. Basically (pun?) her basic makes Rey seem like a tank. Ok Im done
And that's mullato's in-depth, suggestive review of the 2.
