I mean of course, we're all just sharing our views. I am simply disagreeing with the premise of the thread entirely and am trying to do so from an unbiased point of view. I don't like, want or care about Joker or Catwoman, but there are plenty who do and they might have superb play styles and add a lot to the overall game aesthetically, meta/game play wise etc. It's very silly to write off characters with minimal to no basis.
If they're well designed and great characters, that means you're complaining simply because they're not who YOU personally wanted. I wish Hawkgirl took the place of one of these Batman characters(there's an insane amount of them), but I'm not gonna argue they're wasted slots and shouldn't be included simply cause who I wanted isn't involved even though she would add something different to the game too, survived Injustice 1 AND had a unique play style that was unlike anyone else in INJ1.
I wanted Vixen over a lot of characters including Cheetah, she was my second most requested new character after Blue Beetle, but I don't think it's fair to oversimplify characters and make them sound boring, even if they're not. Cheetah's backstory, looks etc isn't like anyone in the game. Even not seeing her play style, there isn't anyone like her on the roster. The Society is also going to be a thing in 2 and she has been a prominently featured villain among all those people for a long time. I don't know anything about Overwatch girl, but that sounds like hyperbole to try to make Cheetah sound super bland.
Trying to put her in the same boat as the overexposed Batman characters makes no sense. She also shouldn't be included because she has ACTUAL powers and can give Wonder Woman and other powerful RELEVANT fighters a run for their money. Cheetah isn't overused or everywhere so she should never be compared to having Batman, Joker, Harley, Bane, Catwoman, Robin, Deadshot, Scarecrow, Poison Ivy and most likely Mr. Freeze. Cheetah isn't squishing out a bunch of people and neither is Cyborg.
We both agree that there are too many Batman characters and others could have got the shine, but where we disagree is that despite that I'm not gonna push for their removal as part of this is a popularity contest, if the demand wasn't there, there would not be so many of them.
You got Hal Jordan Green Lantern and Atrocitus (that's two characters from one of your favorite comics/series). I really like Cheetah (you clearly don't care for her), but I don't care about Hal Jordan and don't need to as I have several other characters to enjoy. Hal isn't a waste, neither is Atrocitus or anyone else for that matter.
