I can see why they scrapped that idea
A strategy game played from a 3rd person perspective of a hero unit would be really weird
I dont see how it could work as a strategy game since you wouldnt be able to do stuff in your base while your fighting
I guess you could do it if you automate the base, but then it would be more like a tactical game rather then a strategy game
I also see why WoW is the way it is now
They had the leftover ideas/assets from their first wc3 concept, and were like, we could totally make this into an rpg but then they realized they didnt have anything else really so they just combined the ideas/mechanics of all the other MMOs that came before it
