None of those three are BGs staples anymore, but out of the group, Luke is probably most valuable because of his ability to deal with some of the mystics and ability power rate in general.
I still use luke a lot in bgs, like kindred is a real pain in the arse and luke makes him a joke.
All 3 are attackers and unfortunately are no longer top options. Not really because they're bad, but because Kabam has shadow nerfed them:
(1) Hulk: many BG metas and several new defenders just do not allow Hulk to do his stun lock rotation.
(2) Luke Cage: can still take some tough defenders but there are faster more reliable counters, such as Torch, and Spider-Woman. But probably the only one out of the three that has not been shadow nerfed.
(3) Tits: the intimidate just doesn't work most of the time, so her rotation doesn't work. Before Kabam did this, she was one of the very best BG attackers in the game.
really appreciate hearing this advice. I also have an sig 60 spiderpunk; would he be a better choice over these three
