I don't see this as "the leak" simply because it doesn't mention any game mechanics wide/good/detailed enough to be the only mechanic as soon as you enter.
A few campaigns with cosmetics and some items isn't going to cut it. Let's say we have a mission table. That's still not enough.
More than similarities is that they can pull a mythic path like in Pathfinder so for example
Warrior
DK
Pala
Can do the Dragon Guard as extra Tank spec.
The issue is that Tinker will be just Hunters almost?
Cloth DPS get nothing but Healer? Unless the CHRONOMANCER is a typo and is DPS
On silken ebony wings the harbinger of death arrives.
This leak aligns with what I have been predicting so far, which means that it must be the correct one.
No leveling would be one of the worst ideas ever.
Has anyone considered that "WoW: Dragonflight" could be the new mobile game? From the first moment I thought it was a weird name for an expansion because in WoW the dragon lore is about.... dragonflightS. So unless all the dragonflights come together or some other lore reason - which I am not excluding as an option, just speculating - it would have made more sense to have the exp be called The Dragonflights. However, if it is the mobile game it makes perfect sense because for all we know, it could be a dragon riding/flying simulator So Dragonflight in that case would refer to both the lore entity that the Dragonflights are and the act of flying on a dragon. Well, 2 more weeks till we find out I guess.
