What's your order of operations when you start a new campaign as Drazhoath the Ashen? Personally I always wipe out Tretch then usually Greasus comes for me so I wipe him out, then if Grimgore and Timurkhan are occupied I'll consolidate the area around Naggrund and take out the remaining ogres, greenskins or undead rabble. I usually ignore Imrik entirely, maybe I should mix it up tho.
I saw someone on here say they ally Greasus and keep him as a trade partner? I genuinely don't know how to pull that off (at least on VH/VH), if I ally Greasus he always just break it off and attacks me later. My most recent campaign Thorgrim declared war on me but didn't attack (okay?), Greasus went to war with Cathay and then Ghorst attacked me (very weird) all before turn 30, I love the variety in this start lol especially compared to Zhatan (my other goat).
