So if dps queues are so long....

[Sylkis]

I really don't see how people can argue that a 1:1:3 ratio wouldn't decrease queue times for DPS. It is just a mathematical fact. Look at world of darkness and syrcus tower if you don't believe math.

I shall attempt to challenge you with something I learned recently: Induced demand

I think that increasing the amount of DPS that can queue will increase the amount of DPS that will queue, because there are people who find queueing as tank/healer more convenient even though they want to play DPS. Some will switch when it becomes more convenient to queue as DPS.
And so, nothing changes as the proportion of DPS stays the same.
