My computer ran everything up to and including WoD just fine. This system is less than half the game's age. It's not a new computer, but it's not so old that being unable to run WoW makes any sense at all; and it ran the game perfectly up until Legion. Now it's basically unplayable, FPS drops to <15 constantly and the client frequently freezes for seconds. It's not like the graphics are so improved that this makes sense.
