Honestly probably goes back to Pre-DLC Vault days where every one wanted Warlock raiding parties and being a Hunter meant you were going to get "carried" because Bungie decided not to bless us with a DoT Grenade/Super. Rather than being kicked for having a bad weapon set up or low level, you got kicked for being a Hunter. Most of the time (my experience) it was Warlocks demanding Hunters get kicked or left out, they wanted other Warlocks so it was easier to cheese. Titans, as usual, didn't really give 2 f*cks. PvP stuff probably didn't help either but this is my first guess. [spoiler]Plus Warlocks are just a**holes :p And Hunters blink better anyways.[/spoiler]
