all of them are unplayable except for comp, range, and custom matches
DM is the worst game mode ive ever played (im not kidding) its filled with people who sound whore you and you just die due to a bad spawns
the other game modes are bad because you cant leave them. why has NO ONE questioned riot on why you cant leave an unrated match? it doesnt hurt anyone because there is nothing to lose. ive never understood it, and even though you only need 4 people to ff, that still isnt guaranteed.
and b4 someone says "why ff/leave in unrated or other game modes, its for fun, just play it out." if its just for fun, why cant i leave if im not having fun and the other people can still have fun in a 4v5, they just probably wont win.
sorry for this dogshit rant, but the game modes have always angered me with the strict rule
