I pulled Electra out of my PVP team in Marvel Strike Force, and replaced her with Jessica Jones. One of JJ’s two abilities gives extra ability energy to other characters, and that adds a level of unpredictability to the battle that makes it a lot more interesting. If you hit that on her first turn, and Wolverine gets 1-2 extra ability energy, all of a sudden he’s firing off his ultimate single target finishing move on like turn 2-3, and that can change the whole game.
Of course, now I’ve got to change out Luke Cage too. The problem is that extra energy can go randomly to anyone, and if Cage gets it it’s essentially a waste. He doesn’t benefit from extra ability energy. I’m looking at the Hulk for that role.
