For those that do not know Anet added a 2v2 arena but is only accessible via custom arenas. I and many I know enjoyed them, however anet failed to offer further support other than "they now exist in custom arenas."
While I can see a-nets fear for adding it to an unranked or ranked queue due to potential additional queue times why not..
Make a few 2v2 automated tourneys to mix it up and add to the AT rotation!
Full Counter is supposed to counter everything, why else is it called FULL Counter... Just like 100 blades should really hit 100 times so you instantly die to retaliation.
