Storm
Storm is one of the most powerful X-men but I feel her abilities in this game is very much lacking. At the moment, she only has the ability to control lightning. With her powers, she can control weather and its elements - snow/fog/wind/heat. I think she should have this buffs/debuffs in a way similar to Scarlet Witch's VoF (ie random) or could be based on her health.
At start/100% health - she applies Coldsnap (snow)
75% - she applies Incinerate (heat)
50% - she reduces ability accuracy (wind)
25% - she evades projectiles and her SPs become unblockable (fog)
Its about time Kabam gives her the powers/abilities she deserves.
