For a game supposedly about war and the crafting of warthings, World of Warcraft [official site] doesn’t have much of any of that. Mostly the Horde and Alliance stand on opposite sides of the warhall sneering and occasionally yelling e.g. “You’re rubbish you are!” The Warlords of Draenor expansion did add a little warcrafting, though, letting folks build and upgrade their own garrison.
Now Blizzard are expanding that to include warboatcrafting, rolling out shipyards. You won’t sail them around engaging in actual war, of course, but at least you can feel comfortable that you totally could and would if those cowards would dare come round your manor.
