Exactly.
Happens the same on WP and AK.
A newbie can't really "learn" them if everybody else is speedrunning/facerolling the instance.

A newbie will screw up the speed run if they don't know how to speed run. They'd have to be taught the process and successfully learn the process. Sorry you also missed the point. By being level 50 they already passed the tutorial.

So you progress your gear but not the dungeon you do?
I always thought that progression was about the level/difficulty of the instance. In WoW terms, a progression guild would push forward the Heroic raid until they beat it, only doing normal mode bosses if they're completely impossible with current gear.

The reward for progressing past an instance is better gear and becoming more powerful.
