My review:
Got an alt from 60 to 70 doing half of Waking Shores in a few hours. That with level scaling really trivialises what a level means.
However if I can do 10-70 in Dragon Isles and with the warband reps/questing, I can see myself playing multiple alts unlike previous expansions where I would have one max and it was a lot of effort.
MSQs are bad for MMOs and we have had it like this since Cataclysm, there is no reason to have us do most of the main quests in that specific order and not even include the dungeons. Make it a short intro to the zones and give us the freedom to organise it how we wish like in Classic.
Dungeons are very poor compared to the competition, I think these are the worst ever and Classic had the best ones, but the open world is the best I've seen in an mmo. Delves have potential, need to see the higher tiers.
The new tradeskill system seems amazing with a short grind to unlock the recipies and features then a long grind to get all the incremental perks. Dragonriding is perfect, what a feature! I know these are Dragonflight features but I didn't play that, so like others I may be judging this more positively than Dragonflight players are.
The story is gay, but less gay than Shadowlands and Dragonflight.
The alt friendlyness, open world and tradeskills put this as a top teir expansion alone.
Making a tier list doesn't work because each version of the game values different things how do you weigh the accomplishment for vanilla leveling and epic open dungeons against the excellent new tradeskills and flight mechanics? Gotta split it between generations of the game.
