They needed new sets to get people into pvp.
Matchmaking to keep the new people actually IN pvp, instead of 1 match and never queueing again.
Unfortunately it destroyed queues for the r30, who are now faced with repeating the same grind they have done before yet with much higher wait times while STILL being grouped with mostly new players. Making the matches feel like a roll of the dice thats over in 10 seconds.

I wonder how possible it is to merge all datacenters just for pvp after they went to all the trouble of you know, seperating them. Or how laggy it would become for melee and tanks. I dont get why people transfer and pay even more money for such things, at that point why not buy or play a FREE pvp game that actually has dedicated servers and under 3 min queues.
