I suspect you are correct that he has not seem you stream yet given the sheer number of streamers doing D2R right now. You are relatively new to streaming where your first diablo video was in the past 2 weeks. I have watched your live stream twice. You clearly enjoy unmodded D2/D2:LoD.
There are a ton of twitch streamers. Many do play modded D2/D2:Lod and prefer those in comparison to the battlenet version.
