The only real way to solve DPS queues

[Ghastly]

What we need is more tanks. With dps you have so many choices that you want to play them all (or a lot of them). For tanks it's the opposite, there's so few of them that eventually you're just basically on the same job all the time, maybe on an alt tank here and there. If there were 5 tanks I wouldn't mind queing as tank most of the time because there would be so many to choose from.

Barely anything will change when throwing more thanks to choose from. You get, at best, maybe something similiar like when HW came out and have less queue times for a month or so, but then it all falls back into place again.
Once the tank players and job completionists have capped the job, it's all back into being tanks as AIN's again for regular dungeon runs.

Playing tanks, like healers, is more of a mindset thing than just 'for fun'.
