Yeah, maybe but the dark portal to other world is very different than taking a portal to the afterlife and all that is means. Also, taking a portal is very different than using a spaceship to go to another planes like it’s the Millenium Falcon.
Even in those times, lore was grounded.
Agree, Legion did a lot of nonsese in 7.3 pushing us to kill a damn titan and converting Sargeras into a mean dark cloud.
And with all the cosmology chart nonsense and the decision to make us travel to outer space and other planets in future expansion this will not age well. If Lightforged Draenei were the Protoss of Warcraft I dont know what we can expect from the future.
