Oh I know it isn’t a long term solution in terms of online functionality - if you don’t mind not having online right off the bat, you’re better off using a disc to install and updating manually. But if you don’t want to go through too much trouble (at least for the time being), you might want to use the PTR client.
I was talking about the original classic WC3 and about getting a disc, not a digital copy. And the original creators do deserve the money.
