For competitive first person shooters, yes.
You keep saying this, but what pc gamer uses keyboard and mouse for games other than fps and rts.
You are flat out bullshyting with this statement. You are arguing that a keyboard is equal or better for literally every type of game.
Breh, league of legends does not look interesting. RTS games don't interest me. I don't like watching the action happen on screen while I'm flipping through menus micromanaging shyt. That's not fun to me.

Newbie shyt?
Hack and slash?
You didn't download shyt. You watched some videos, now you gonna act like you played the game? Lol upload some of that beastly gameplay.
I'm not comparing it to quake, apples and oranges.
Hardest single player game out is newb shyt.
I get the feeling that you don't play anything other than those Korean LOL games and old ass shooters that were hot when i was 12.
