There needs to be a way to remove dungeons from roulette?

[ForteNightshade]

Yes, just like the trials roulette is still a roulette despite not including Amaurot. Letting players avoid specific dungeons isn't going to cause the entire system to collapse. Participation may even increase if people didn't have to worry about being placed in their least favorite content. If certain dungeons are really despised by the majority, a separate option could be added to the duty finder to prioritize queuing into first timer dungeons or unpopular dungeons in return for more XP/tomes/whatever.

It's far more likely queues would become unbearably longer for certain dungeons than increase. If you could veto five dungeons from Leveling, I can all but guarantee which ones would be picked.

Sastasha
Copper Bell
Toto-rak
Tam-tara
Aurum Vale

And therein lies the problem. Four of them are story required, which means new players could be waiting hours. Amaurot would have a similar problem simply because of the ilvl sync.
