Duty finder - Front line - problems

[Cleffy]

There are lot of issues regarding the Front line-duty finder.

it doesn't follow a rule but it seems random and now I explicate why.

-Me and some of my fc have tested the duty finder regarding the Front lines.. result:
We joined in 6 = 45 minutes of waiting time so we disbanded and joined alone.. after 1 min we were all in the same party.

-IF the alliances are not full, the person that join it the moment that the fight start is able to join an alliance and fill it = this person have the priority compared to those who are already waiting the front lines. it means that re-queuing every minute makes things faster.
I also did other test about that.
I had a time wait of : 12 minutes with "join party in progress" active, I restart the queue and It sent me on a front line started 1 minute before.
What it means? I had the higher priority compared to those who are already on queues.

I'm sorry for my English, and please test it too because we must find a solution, it isn't fair.
