Oh yeah... I don't like the guy all that much. Don't understand why he attacked the Professor... Edge, well, Edge (the M:tG youtuber, not the moderator here) has made some bad decisions in the past, and asked his fans to bail him out. I'm not really a big fan of the guy, he seems a little "douchey" to me.
Also, he's not solely responsible for making the MTGO community shit... it was a pretty shitty community to begin with IMO... at least it was when I was playing. MtG Arena doesn't seem that much better either, but at least emotes are limited (and there isn't any chat)
