Question: Does Circle of Slaughter have a different queue for TVHM Mayhem 3 (vs regular Mayhem 3) ? Or are we all lumped in together?

If we are separate, how is the queue/population in TVHM Mayhem 3 for Circle of Slaughter?

Im finding it difficult to find groups for Mayhem 3 at this point and Im wondering if it everyone is in TVHM Mayhem 3. Wondering if the population is higher there and should I start TVHM at this point.

And Ive never found a group for Proving Grounds.

Thanks,
