As you said, if theyre only playing solo online, there is no difference between that and single player offline. If thats the case, then why are they even playing solo online? Incase one day they wanna make their char a pvp? Then it got there by cheating. Solo or not, keep the hacks and cheats off bnet.
But, the OP was referring strictly to offline single player mode. Which i agree with. If theyre banning people for using single player cheats, they should ban their featured streamer dbrunski, he uses hero editor for all his build guides (IM NOT SAYING HE SHOULD BE BANNED. Its single player after all)
I don’t think Blizzard would have any way of knowing if you did in the first place. Likewise, Mods are allowed in single player offline play. So, it’s not a big issue.
You’re not wrong, but it’s not the recently cracked versions that sent Blizzard down this road. It’s the ease at which their old games could just be outright copied and pirated.
