If you're a character loyalist...play him. If you're only playing to win (the fgc pays crap guys -- even Jwong isn't traveling much these days since he's actually making real money off twitch and Daigo is a nurse.) then pick another character. Mkx all in all has a way more diverse viable roster thus far. Yeah, Kenshi isn't that ex armored flowchart and you've gotta work for your wins now.
If that's not for you...pick a character with better tools. Reo and Jr aren't loyalists. Daigo and Wong aren't loyalists. Do you want to consistently win or do you want to be a chatacter loyalist?
Hopefully kenshi and kitana have some undiscovered tech or get some better normals if they really suck this bad but at least this isn't Mk9. Bottom tier exists in every game....and well...kenshi was pretty downright dumb in mk9 so I'm glad that he isn't a complete transfer.
Hell...smoke, kabal, noob, cyrax, sektor, and baraka aren't even in the game and those character loyalists have a right to complain but they've barely said a word compared to this. Very stupid all in all. Ketchup and mustard don't even have their characters and they're not throwing a shitfit.
