I forgot about it awhile ago, until i saw it in my addons folder. I know it was really popular during siege, but then blizzard fixed premade groups. anyone still use this and if so, are there alot of groups still being formed on it?
In addition to adding the premade finder, Blizzard made some changes that limited the ability of oQueue to form the mesh network they used to track stuff. So, while it still exists and all, it's now based on the same backend as the premade group finder in-game. Which is to say, yes, lots and lots of groups, but you don't miss out on anything if you don't use it.
