I would definitely try an official VR XI.
But knowing them, it would be on special servers, not compatible with your current progress, level 75 only, and start from scratch.
I bet though, many people would come back in full force of VR mode were released fully compatible with current characters and content. Way more people would be into that than lolXImobile.
Are there any VR MMOs even out yet?
Would be a smart way to test the waters, and also let us be free beta testers for SE's VR capability.
