The second part is a non-argument, get over it. That's just the name of the game, which was inherited from an RTS game where crafting buildings and troops was an important part. The world in WoW isn't called Warcraft. No planet, continent, country, village, nothing in the lore is called Warcraft. It's nothing beyond the game's name, engineered to ride on the popularity of Warcraft 3. Even Blizzard themselves saw it like that, as, once more, the game didn't have "PvP servers" at its roots, those came later, and the non-PvP servers were then called Normal servers.
