A little bit rougher than I would have put it, but it's pretty true. I wouldn't say people who primarily PvP are asshats, but I would say a higher ratio exists in PvP than any other type of game. Anytime you get PvP competition, it's a little more "toxic" as people put it. It was like that when I played hockey, (Canadian) football, soccer, baseball. Even in Phys Ed class, the spirit of competition brings out a different side of people. Similar attitudes carried on when getting into StarCraft, Unreal, CounterStrike, AOE, WC3, Halo 2, MW2, etc. If you really want a fair comparison between LoL, and WoW, do some BGs or Arenas in WoW. Even back in 2005 on the release of WSG and AV, people in BGs raged and whatever all the time.
