70 bracket is obviously not the most active bracket. . .
Yet it is still very active.
Yeah, have had two Av's going at once,
Couple times, actually. Couldn't be arsed grouping with about 7 others before, didn't want to setup a group/second group, we all queued, several of us didn't get into the same Av.
And as for Activeness, 70s are extremely active, not sure how they would compare to 19s, assuming they have a higher population as it's quicker to get to 19 then 70, of course, and as for other brackets, no idea.
