Mmmm.

Elder Scrolls Online syncs every dungeon, every zone, everything. And they have the champion system which is a merit like system and it does fine. If it weren't for the champion system, you wouldn't even know who is Level 15 and who is level capped.

It can make forming groups easier and more enjoyable.

But the cost is that no matter how strong you get, the content is stronger than you. Hamster on a wheel. I like tangible progression. It's not like roulette is the only means of progression, especially when Eureka, new relics, and other stuff comes.
