I’m just saying… In my experience better pets and more pet aggro always wins in deep SR. Especially with no Ishtak. If pets lose aggro in a critical moment in SR 100+, those 2-3k health from maxed Spectral only buy you a fraction of a second of survival. So I’d rather put more meat on Briarthorn’s bones and give him Ground Slam. But I never used that conduit. Does it pull enough aggro to Blight Fiends?
As for my gt, I only played classic Ghol, but the general principles apply here, too, I think. After some testing of my own ideas, I concluded that Sigatrev’s Gholiath is probably the best setup possible for survival. With RE changed to Ill Omen, ofc (he made it before the Ill Omen buff), and the extra points dumped in Ground Slam until Taunt.
