I'm sure it totally does, since I started an account (just to play relaxed without people flaming and the kind) and maybe the first 5 matches were with rookies but up from then, it's worse than playing in my main account, people are much meaner and disrespectful xDD sometimes they are like are you idiot or something!?!? and i "play myself" a fool like "i'm learning man, i'm just level 6" they say they are too and when they mess it up later and u tell them anything they get so cocky like "i'm fucking diamond 3 in my main account u fucking stupid" or whatever xDD, like being in a high elo makes it less awkward to flash on the spot xD.
the thing is all the players in my games are smurfs, not a single noob, and they are even more toxic than the regular community, wich is "delightfully kind" on its own. Sorry if I made any mistakes writing xD
