Easy Way to Increase Max Level Content

[ElroyDrundan]

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?
