Copy/paste jobs are fine when you actually copy/pasting everything over.
When you half ass that, then the backlash is even higher. Marvel 2 copy/pasted everything from before... it did it right at least.
It's like... you copy paste over Firebrand, Nemesis and Arthur... but don't copy/paste over Wesker, Zero, Vergil, Joe, Amaterasu, Phoenix Wright, Dormammu, She Hulk, MODOK, Iron Fist, Ghost Rider etc. We know they are capable of doing it and we know there will be more copy/pastes in the future through DLC... it makes the whole thing shady, as if they are waiting to sell us copy/pasted characters as DLC.
Imagine a Veterans Season 2018 where they sell us Wesker, Zero, Vergil, Phoenix Wright, Joe + Wolverine, Deadpool, Magneto, Storm, Dr Doom, Super Skrull.... all of them being copy/paste from Marvel 3. No one is going to feel good about that.
