Bornakk revealed a welcome bit of future patch info on the general forums recently, announcing that there is an incoming improvement on a future 2.4 update that should lower arena queuing times across the board. This is definitely welcome news for many of us, although those who counted on getting chores done during the queue might get a little disappointed!
We've heard in the past that blizzard didn't want to rush in to any quick fixes and was considering the queue time issue carefully, so hopefully that means they've found a solution that will stick. Thus far, aside from the occasional mishap from a sneaky warlock and the lack of certain expected class changes, they seem to have had a smooth and well received patch on their hands.
While some people were asking for a hot fix in the thread, Bornakk assured them that the change was complicated enough that needed a patch. Being someone who often ends up running his 2v2s on Saturday or Sunday evening and experiences queue times that sometimes climb to 10 minutes or more, I'd say the wait will be worth it if it means I don't have to wait around quite so long in the future. Faster queue times, at the least, mean I can fit another daily or two in.
