I for one don’t see the problem, the big level cap decision is “Which covenant do i join?”, so it stands to reason that going through the background story of said covenants is a pretty important thing to do for levelling up (Not everybody lets Wowhead or icy-veins decide for them), and they’re IMO doing a pretty good job of it.
How much fun this will be on alts remains to be seen, but so far (Just finished Bastion on my main, hit level 54 on the “Go to Maldraxxus”-quest) having a more involved story than the usual “A farmer has pests in his field, get rid of them”-fare makes for a nice change.
