I'm bringing this up after trying to queue for Duty Roulette: Frontlines.

Whilst I was waiting for entry, already queue'd up for 21 minutes, my friend decided to queue up for his respective roulette as well. 14 minutes later, he got entry and I didn't.

When he got back out of his match, he queue'd up again and he got instant-entry. Whilst my queue accumulated up to 52 minutes. Lastly, while he was doing the match, one member of his team left so there was a spot open and again I didn't get entry. I tried to queue up alternating between roles every minute and I just couldn't get in. So I gave up.

Extra info:
We were queue'd as the same role at first
We're in the same Grand Company
We both used 'Join in progress'
He's rank 11 while I'm rank 2

The only difference I see is the difference in rank. If someone could enlighten me as to what happened I'd be happy because at the moment I don't feel very invited to start PvP'ing if I keep getting excluded due to my rank.
