Frontlines Duty Finder queue acting strangely

Always

Character Name:
Altena Trife

Race:
Hyur Female

World:
Excalibur

Class/Level
Any class, Level 50

Party/Solo
Both

Steps/Issues:

- When queued with 2 or more players, the duty finder occasionally does not register both players confirming the queue - and withdraws you (even though on both characters you see the total amount of players such as 72/74).
- Often while waiting in queue, the estimated time may be around 20 mins, however after 60+ mins of waiting in queue, it does not pop. After cancelling and re-registering, it can pop as soon as 5 mins.
- While a friend was in a game with 6 empty slots, Join in Progress would not trigger, until I changed to a healer. After finally getting in, I noticed that there were already 3x healers in my party. If there are job requirements they certainly aren't functioning correctly as there are often parties with no healers or tanks at all.
- The biggest issue is the extremely long queue times, even when the estimated time is below 20 mins. This problem increases as your party size increases - as the queue time seems to multiply while in a party larger then 2.
- If 2 people queue in separately, from the same GC, with the same settings, on the same class, quite often the person who started the queue later will get a match before the player that started the queue sooner.

If there is some sort of rank matching system, please at least remove it from Frontlines, or widen the spectrum, as the queue times are beyond ridiculous in their current state.
