I've seen this statement from a few people who advocate for keeping a queue system in the game. My question is why do you feel this way? Just because a pug that is listed in the group finder tool (which is one of the best features Blizzard implemented into the game) is asking for certain types of players, does that mean that they are automatically not worth joining because they are formed by real people instead of a machine or automatic queue?
I never understood why people (especially people who choose to play an MMO) would not want to interact with any other players at all. It just doesn't make sense.
