All dungeons should have minimum ilevel requirements?

[SDaemon]

Not really. They're saying that the player would be required to reach the minimum ilvl before being able to queue up. For example, a lvl 65 queueing up for leveling roulette would need to be at an ilvl appropriate for the highest dungeon of that level (Bardam's Mettle).

If SE were to set minimum ilvl requirements for leveling dungeons then the player in your scenario should simply be put into a dungeon fit for their ilevel, not barred from leveling roulette entirely.

Which is missing the other half of the point, that because people want the rewards, they will cheese the ilevel so that they can get the reward with the least effort, eg equipping the ilevel 50 relic gear to avoid any HW or SB leveling, even if they're level 70.

People already admit to doing this with the Alliance raids.
