Just checked my wife's laptop (she refuses to play on a desktop) and the system specs meet the minimum requirement aside from the graphics.
Her laptop is a Dell 7000 series and it uses Intel HD Graphics 4600 series. I know it is cringe worthy but it has served her through all of WoD through heroic raiding.
Anyway point being I don't have the budget to get her a new laptop at the moment, so I want to know if she could run Legion even though graphics don't meet the minimum. I do know that WoW has a history of being very forgiving for low spec systems but she did have some video driver errors on a previous laptop, I think during Mists.
Anyone have a guess if she'll be alright for a while longer?
