Well, I moved from Chaos and back to Aether the day before the servers went down for 4.2. I'm an night owl, for the most part...so the queue times are much better for me over on Aether and I don't notice anything in terms of lag.
I queued up for a PvP roulette earlier and was pleasantly surprised that a five minute wait resulted in a 72 man Shatter. Quite refreshing after only seeing 24 man battles for the past few months. I put it down to the impressive looking new gear, though. The new orchestrion roll certainly helps too.
