ilvl cheese is the least of the issues with it. It's the lowest lvl and mandatory so everyone doing alliance raid roulette is in selection.

Making the others mandatory would help, some but with it being the easiest, it would need to be correctly rebalanced which SE should have done with the stat squish but didn't, means people will ilvl cheese it still. Moving it to msq roulette is completely not viable since the dungeons in it are 4 man's, they'll never pop as it stands now.

The current msq dungeons should be scooted over into the leveling like they used to be and remove the lock on cutscenes. It has trust, do it with trust to see them in full. And in it's stead the CT raids should be alone there, as the cheapest, easiest and fastest way to fix this.
And what about void ark? Nothing, it's fine. That's a non-issue.
