Theoretically if WC4 was real

I don’t think there’s any chance of a WarCraft 4, ever. What I DO think is possible is a full remake of WarCraft 1+2+BtDP, which would obviously only have two races in SP though I could see them adding an option or two for MP only. Actually Draenei could be an option as a SP enemy race if they added some Horde missions from before the opening of the Dark Portal, which would in turn make them a viable MP option as well.

Bruh moment right here

Maybe I’m just confused about the lore, but didn’t the scourge splinter off into the forsaken? And everyone hates the scourge? Why couldn’t the same thing happen with the Naga and Night Elves?

Isn’t there actually already a similar theme with good and evil Dranei?

Really depends on what the gameplay is intended as. It is very well possible that it gets streamlined towards race heroes + race specific units. In such a case every WoW race would be represented as a separate selection.

On the other hand it might be optimized to tie in with the “Hoard vs Alliance” theme, in which case there might only be 2 choices.
