Now, as a disclaimer, I have absolutely nothing against Warcraft as an MMORPG like with World of Warcraft. After all, it has everything that makes an MMO cool, such as the 25-to-40-man cooperative raids on high level, end-game dungeons.
It's just that I almost wish Blizzard would go back to making Warcraft an RTS game with a possible Warcraft IV. Nowadays, I seem to be obsessed with the idea of building and managing a base and army, because it's almost no different from party or team management. Technically, base and army management involves division of labor, like building a party or raid; the buildings mass-produce and research new units and unit upgrades, while the units themselves defend their buildings while attacking the enemy's. Likewise for a 25/40-man raid; half of the team are tanks/defenders and healers/supports who sustain the main attackers, like buildings, and the other half are the main-attackers themselves, whether physical, ranged, or magical, similar to units.
