Wait so you load one thru steam and one thru battle net and that works?
This does work, yes.
I believe still need PE to close the instance check though.
My friend who uses says he doesn’t though.
Pc is fairly ez as well.
Bnet app = allow multiple instance of bnet
Seperate game folders for each copy.
Load one, close “check for instance”
Load second.
In my case I use command line argument with “region+acct+pw”
