@IfrianMMO Well this might be a little different I imagine. Since xbox runs a stripped down "special" version of windows 10 for the OS it might be that the vast majority of beta testing on the xbox is almost 1:1 for the OS side of things making a PC beta not needed so much in that regard? That being said assuming different hardware config optimizations can be transferred from the JP version to ours with minimal issues the only thing I could see in dire need of testing are the servers.
I think they should do a stress test for the servers before release because we can all agree that any mmo can stress and beta test as much as they want but no one is prepared for day 1 traffic let alone the first few weeks. Not having at the very least a stress test might be a mistake but who knows. they might be doing something internal that we aren't aware of leading them to think that PC testing is unnecessary? I still think its a mistake if that is the case but eh, we'll see.
