What would you suggest me to go with? Lets set it for, say, single target serenity.
Most resources would tell me to go kromog (obvious choice) + gruul or butcher.
On the other hand, Skull of war mostly aligns with every burst (serenity + kromog's + skull + whatever on every serenity), although it is very low rated in AMR
Sims with kromog's + any other choices give me almost the same result (40k +- 300 )
I'd stick with Kromog's and Gruuls until you can get Skull upgraded, then I'd take Kromog/Gruuls for cleave and Kromog/Skull for Single target. Forget about Butcher's.
