there is no denying that it happens to most, yi players can be snobby jerks, rammus's that are losing feel worthless,
poppy players just don't give a crap because people will always say f*** poopy which how i learned not to bother with complaining. However it also depends where you play, team builder/ rank etc. in rank there are alot that will rage quit if they aren't ahead. Not because they are worried of lp, but their kda and want to show off, but it happens team builder they most times don't but the riven's people find clmbing to 30 are the same ones going into rank like that
