I don’t have a problem with guest characters, its just a matter of if I like said characters or not lol I love all of MKX’s guests because I just happen to be a huge fan of each franchise those characters come from. Rash I had never heard of really until he was announced, but I still think he is really cool and looks fun. Arbiter and other XB exclusive shooter characters I could do without though, mainly because I know little to nothing about them so I personally don’t really care about them and would rather get a new KI character lol
So yeah, for me its just a matter of if I like the particular guest or not.
