RDF Queue

OK so, if we queue solo as tank or even heals, most of the time it's instant 24/7/365. Something has dramatically changed with the RDF queue in the last few months and when we que as tank with 1 person, or even 3 dps, it's a 30+ minute queue. Something is wrong with the queue. Has something changed? There's absolutely no reason that if we are queued solo as a tank we get instant dungeons, but when we queue with a DPS or healer it's not instant? This makes the RDF queue broken, does it not? Please fix this immediately as it's a major flaw. If it's instant queue as solo, it should then also be instant if we queue with a party. There's an obvious flaw here.

well baisclly how the queue for rdf works is that the game will try to find the best team combination will suit you so the majority of ppl are dps and then healers then tanks so when a tank queue solo the game will try to find a team that needs only one tank which is always the case so when a tank queue its instant and thats for all the roles but when a tank queue with dps then the game will try to find for him a team that has spots for tank and dps which is rare case cuz all the teams usually needs tank and healer so it will take a long time to find a combination or it will just place them on new queue and then you need to wait for 2 dps and healer. hope that make sense
