I believed, reasonably I might add, that the vast majority of people who queue pvp queue for either The Feast, or for Frontline Roulette. GIven that pvp does not impose party comp restrictions, one would THINK that queueing for a specific frontline would create an instance for it for the people queueing the roulette.

Yet, this does not seem to be the case.

I have tested this thoroughly. Queueing for frontline roulette results in queue times ranging from 2 minutes to roughly 20 minutes, depending on the time of day. EVERY. SINGLE. TIME. you get queued into Shatter.
If 1 person queues specifically for Seal Rock, then the people in roulette should get put into seal rock with them, correct?
