Characters that need buffs
I recently got a 6* Red Skull and he seems to have some very good abilities, but (and it's a big but) he hits like a wet wipe. He's so weak so his abilities may literally be only good for alliance war defence. I've saved for months upon months for character I may never use. Not complaining about the RNG but Red Skull is the main enemy of Captain America he should be a decent character to play!
Magento, another character in need of buffing or reworking. Main enemy of the X-Men, leader of The Brotherhood and an overpowered mutant. In game, awful. Has the advantage over metal using opponents which in theory should be awesome.....alas it is not and it's not ALL people who use metal.
Others who need buffs Cyclops, Colossus, Groot.
Any others feel free to comment below. Hopefully Kabam will take note on our thoughts.
