I think if enemy HP in low level dungeons had been increased by like 1/4 or 1/3, and the party composition changed to be Tank/Healer/DPS x 3, DPS queues would have been a lot better without turning dungeons into a total faceroll. I suppose having a new tank and new healer class will help some, but even so players have a lot more DPS classes to level than tank/healer, and when you're trying to level DPS classes, that's what you have to queue as so just going as tank/healer isn't a solution from that standpoint. I mean why not redefine light parties this way, it's not like there is ever a DPS shortage. Or have it scale where if the DPS queues are significantly longer than the rest, you get a party of 5 with more enemy HP. But really, when is that not the case outside of like WoD/ST. I have an alt on Leviathan, where I'm levelling SCH/SMN and get healer queues, and levelling BLM but have learned not to bother queuing for a dungeon I actually want, and just get the roulette bonus on that class once a day and even then the wait sucks.
