Wasn't that the Thorns exploit, though? The switching was working fine, probably still is (?), and it was a necro exploit. There was a 125 top1 clear on Necro leaderboards with a lot of thorn rolls using INARIUS pieces. Yeah, Inarius, while everybody else runs Pestilence or Trag.
Also, video removed. Got a mirror? I'd love to see the reaction to a ban.
