The only real way to solve DPS queues

[Daniolaut]

Increase the new 4-man instances to either 5-man or 6-man instances and scale difficulty / mobs accordingly. Of course this would be too big a job to change all of the current dungeons to this setup, so I am suggesting that any "new" dungeons after a certain point be changed to this.
1 Tank, 1 Healer, 3/4 DPS.
.

I asked/said this a long long time ago.

Was completely ignored basically.

The thread was also on this very subject.

The thread from 2013

This was also why healer queues were instant at release, because they never had to wait for anything ever.

So yes, its going to be much worse come 4.0 for all content.

3 tanks
3 healers
9 dps,

which equates to 3 dps waiting for every tank job for dungeons.
1 tank 1 healer, and 5 dps jobs not in a 8 man group, which equates to 1-2 dps jobs waiting to enter a 8 man duty finder.
