Again, it's unfair, but you either have players who rush, find your own, or have barely anyone queuing for the dungeons. This content is very old. There is literally no reason anyone needs to run it now other than if you're new or if you want tomes. I know what you're saying, people are greedy. But it's tough - if you gate players, they will simply not queue if the reward isn't worth it. Those dungeons are long enough as it is.

If SE were to gate players, they'd probably have to at least double the tomes for this to be worth it to most people. This is all while bearing in mind that a lot of people don't even need those tomes unless they're doing their relic or a small amount of other things. Again, it sucks, but doing this could be more harm than good.
