I can't speak for others, but I'm not one to get upset about characters that I don't know or don't like getting into a game when the characters I like don't. It's silly to blame a character you don't like for your own personal favorites not getting in. I may be disappointed that the Punisher isn't in, but I won't blame Rocket Raccoon (Who I admit I never heard of, I don't read much comics outside of Punisher, Iron Man, and X-men) for his exclusion. Besides, Rocket Raccoon seems like a cool character. Almost like a Star Fox character with attitude.
What does piss me off is Capcom constantly trying to get away with more and more bullshit. It's like with every game they decide to rip us off a little more by giving us less content, more crap dlc, and an absurdly short amount of downtime before double-dipping.
