Easy Way to Increase Max Level Content

The old 50 (Hard) dungeons were Expert dungeons during the patch they came out. For example in patch 2.5 the Expert roulette was Keeper of the Lake, Wanderer's Palace (Hard) and Amdapor Keep (Hard). They got pushed into High Level Roulette (renamed 50 roulette in HW and then 50/60 roulette in SB) once the next set of Experts was released.
Between that and the relic grind a lot of long term players are probably sick of every old level cap dungeon in the game.

I see, I left part way through 2.X and came back at the beginning of Heavensward when they were optional to unlock. This, or just starting post ARR is what most of the people I've played with have done in general, so I thought it was simply optional unlocks, I didn't know that queue was sort of the graveyard of old expert queues. That being said, I still want a reason to go back and play them, but I do understand old players dreading it.

That being said, I'd still like for the leveling dungeons (of a given expansion) to have 70 versions to add variety to Expert. I can count the times I have done Shisui and Bardam's and the lot on one hand (per dungeon) and I have leveled 3 classes (counting SMN SCH as 1) to 70 and one to 66.

I would love for SE to take(ripoff and tweak) from WoW the concept of Mythic + dungeons. You can do harder and harder versions of existing endgame dungeons. You can unlock a harder version depending on how fast you clear easier ones. Each clear drops one piece of gear appropriate to the difficulty level. It provides hard content for those who can't /don't want to form a static raid.

The mechanics stay the same but incoming dmg, mob hitpoints etc increase. At higher levels mobs/bosses also start getting buffs that tweak combat further. It just seems a nice way to introduce challenge and low cost content. It has always seemed strange due to iLvl caps that expert dungeons are easier/faster than the the leveling dungeons.

This is pretty cost effective. How nice would it be to clear a challenging dungeon and get appropriate gear?

The easiest way is to remove "Expert" roulette from the game.
If tomes are a concern, increase the tome gain from everywhere else.

I think something like POTD as an alternative to M+ is pretty good (not that I would be opposed to M+, it's just there is already a progressive difficulty mechanic in the game). They just have to make a new dungeon diver / up the POTD level.
