So a guildie has been having his Domoguard hit for 35k and crit for 72k on the dummy this evening. I tried it out on my alt Lock (who is Affli) and it was hitting for ~7k or so. This leads me to believe it's a bug with Demo Mastery. For the record, I've seen the recount and he does over 40k DPS on the dummy with Doomguard up so it's either the real thing or perhaps a strange combat log issue.
Anyone else seen this - And is it truly a bug?
