wife and I share a computer. both of us have battlenet. I purchased the battlechest but on her account 1 and 2 can’t load.
Diablo 3, reforged etc work just fine on her system.
of course not. it is bound to your account. she needs to buy them herself. diablo 3 and warcraft 3 works differently: diablo 3 runs in trial mode(all base classes available but limited store progress) while warcraft 3 reforged runs without reforged assets.
