Here is my Primal macro if you want to play with it and hopefully improve upon it. I played around with both frostbrand and Searing assault. FB simmed better DPS but was one extra dot/buff to maintain in the rotation. It was better if you used Natural Harmony on your gear. Same with Forceful Winds vs Totem Mastery. Totem mastery is better in sims due to higher fire damage but one more thing you have to tend to.
The Primal macro for now was only a ONE button macro and has not had a lot of in game time on it only on the target dummy. You need to be able to maintain the minimum maelstrom for LL. I also created a few Weak Auras to help with LL procs.
Also not this is a Sequential Macro vs my others are all Priority.
TLDR: It doesn’t flow as well as the 3 button above so I prefer Earthen.
This macro contains 1 macro version. This Sequence was exported from GSE 2.4.04.
