I haven't met him yet. Do you mean EU or US Stormreaver?

I have been the first and only multiboxer for a long time on Stormreaver, until very recently. A couple months ago, there was another shaman boxer named "Rabbit", but I haven't seen him in ages. Since RAF started, there's been a couple teams that I've seen rocket up through the levels. There's at least one group of Tauren shamans over L55 (which I think is tough choice due to movement inside buildings/BG towers, honestly), and I think a group of orcs that I saw in the starting area at L1.
