Considering this is an MMO that is only still floating because of pvp... Seems Like they would encourage The social Aspect of the game... Social Coordination and Team work Is what Works with both PVE and PVP... I don't understand why its frowned upon in PVP..
Well first of all (and I say this being a player who enjoys PvP much more than PvE) PvE is much much more popular in WoW than PvP ever will be. PvP has (and probably always will be) a minor side portion of the game. Also, social coordination and teamwork are not frowned upon in PvP, however in one tier (entry-level tier mind you) it's been limited to help create an enjoyable atmosphere for the majority of players. You still have plenty of outlets for organized play: 2v2, 3v3, 5v5, 5 man battleground groups, 10 man Rated battlegrounds, and Wargames. Until WoW has a better matchmaking system, raid queues aren't healthy for normal battlegrounds.
