Honestly, I hope he doesn't, I played WoW for years and one of his favourite past times was screwing RPers over, he'd occasionally host his events on Argent Dawn knowing full well it'd cause chaos for the server and it did without fail, his fans have the collective IQ of a sponge and the toxicity to rival if not surpass the Chernobyl fallout, concerns people might have are not unfounded.

If he plays by himself without streaming to see if he likes it or not then there likely won't be issues or any negative fallout but the moment his fans come? Toxicity will skyrocket and to the people who think it won't, oh boy, keep telling yourself that you'll see soon enough.
