But that's exactly what I just said, didn't you read it properly? There is no argument to be had here, you are just confirming what I mentioned. OP specifically said people are pre-forming in Frontline Roulette", which isn't entirely correct (as it's solo only), but as I mentioned if they queue for the one on rotation on that day then they can circumvent the Roulette restriction and just enter pre-formed for that specific duty.
It's not rocket science....
