LOL! I usually go with Wolverine, Storm, and Rogue, and alternate between Gambit and Iceman constantly. Every mission or so... sometimes in the middle of them. Gambit and Iceman are my favourite characters, so I gotta' have either one of them playing at some point or other. Did the same in Legends 1 as well. Haven't finished yet though (levelling up in the DangerRoom a bit) so I'm still just fighting my way towards Ironman and Deadpool.
