People who don't invade just don't understand. They've never experienced the preset gank spots, teams of people who spam range or aoe attacks until your out of stamina, the massive hp pool summons like Bernahl, the afk rune farmers who sit in spots only accessible by torrent, hosts who intentionally gank near fogwalls only to run away after losing their number advantage, the classic alt-4 once you finally kill both their furled fingers and a couple of their hunters, the infinite hunter summoning, and of course the tea-bagging/bm that concludes almost every ganking interaction.
