It does still pop on Aether during primetime, but getting the first match to queue up can take anywhere from 5 mins to an hour (or more on certain days). Once you get that first game, the rest usually take between 5 and 10 mins to pop if you keep queuing. Definitely not like it was when it first came out though. I'm still hoping they give Rival Wings a roulette like they did Frontlines, now that it has two maps. That might get more people in there.
