is it? i've quit way more groups because of mutual agreement to quit than i have because of leavers.
and there is no good way for blizzard to make a distinction between those two if they wanted to support this in their api.
like if i have 20% failed runs, does that mean i quit pugs all the time or does that mean i push high keys with a fixed group and we reset the key if it goes wrong?
there are just way to many ifs and buts for something like this to work properly.
