Ilvl requirements for leveling dungeons for past 50...

Well, at 50, 130 is the highest gear, and at 60 270. They could make leveling dungeons provide Poetics tomestones, and make quests give them as well so that players can be assumed to have Augmented Ironworks and Shire gear as a baseline.

53 gear is 130, and 63 is 270.

Those are only replaced from gear The Aery and Bardam's Mettle, and you don't even get 1 ilvl from replacing a single piece of gear.

So 130/270 gear should be fine at least all the way up to The Vault and Doma Castle.

So really only in Great Gubal Library and Castrum Abania should see an ilvl requirement above 130 or 270 in the leveling dungeons.
