WarCraft 3 was already supposed to be something closer to Sacrifice or Spellfore, with RPG progression and leveling armies that you keep between maps.
We only got the WarCraft 3 we know today because Blizzard spun the RPG idea off into what would become WoW down the line.

If we ever had gotten a WarCraft 4 it likely wouldn't have been a RTS game anyway. Probably some MOBA abomination like Dawn of War 3.
