Feedback about team queue IP bonuses.
I'm under the assumption here that the opposing team (at least four of them, Graves was complaining about the others' actions) may just be farming IP with the arranged-team bonus. Maybe they just felt like trolling one guy in unranked play, or perhaps as they said in game they wanted to lower their elo (does unranked have an elo system?) Or just having drunk fun seeing who can get the most deaths?
It could've been just a fluke game, as I've seen them before. But I hope the party IP bonus isn't so enticing they people will try to lose as fast as possible to farm IP faster than a prolonged game could win.
