Regarding the new(ish) Unsportsmanlike Behavior report category
IMO this is the useful report category. unfortunately tho, i seem to find that playing at my elo(low silver) i end up needing to report 5+ ppl most ranked games. I dont know if my definition of unsportsmanlike is to harsh or if everyone that plays is just actually incapable of behaving in a nice manor. i try to avoid reporting ppl for stuff they didnt do(everyone gets mad sometimes) but this catagory is perfect. most player didnt intetonally feed, or use hate speech, or cheat/hack, or even verbally abuse. but i would say many many people display unsportsmanlike behavoir every game(not verbal abuse). i just hope that it is not considered the same way the old "unskilled player" report was(they were just thrown out i belive).
TL DR; Most people seem to consistantly demonstrate unsportsmanlike behavor in >85% of my games and it sucks :(
P.S. im trying very hard not to make this one of those post where someone is just complaining and being salty. sorry if it seems that way.
