Hey there,
I am playing on Deathwing at the moment and I also play some arena 2v2 there. But sometimes, you play against a team which is not joining the arena for more than half a hour. You always get the same team, again and again. This is really boring and no fun at all. People use this tactic to drop their MMR, and since a match that you don't join is not counted as a lost match, they can do that easily.
My suggestion for Lordaeron would be, to introduce a Arena deserteur, just like the Dungeon or the Battleground one. And since the Dungeon Browser is disabled on Lordaeron, your Devs might be able to give non joining Arena Teams the Dungeon Deserteur debuff and check for this every time a team tries to join a match. Or just code it smooth and introduce a new debuff :)
Whatever, I hope you get my point to do something against those MMR droppers.
