"For DPS" If we wanna get technical, this is false.
You're no longer a DPS if you're a healer or tank.
I say increase the the party slots and all like OP said.
No one wants to be a healer and tank all the time, but I admit
that even I just stick with the two because of the abysmal Q times.
I am sure most of us are adults and are quite busy and can't afford to spend
30 mins or more in Q times. I do recommend people using PF to find a tank or heal
for expert runs for example. Here on Aether it takes no more than 10 minutes.
