One thing to remember is that trinkets/racials/abilities require a GCD. So all these abilities you are trying to cast at once, maybe one or two of your trinkets might require its own GCD and if that is the case, you will not be able to macro everything into one button.
I know that avatar blood fury and trinkets macro together easy. I have that macro
Im pretty sure just adding warbreaker to it would work. although you would need to have the mob targeted
/cast Avatar
/cast Blood Fury
/use 13
/use 14
/cast Warbreaker
Um, I use Avatar, Blood Fury, and slot 13 all in the same macro. All three are off GCD if you use a DPS cooldown trinket.
I simply just use /cast
/cast
/use
You can’t use two on-use trinkets in the same macro though because they have an internal cooldown of I believe 30 seconds. That’s why I generally use one on use trinket and one Equip proc trinket. I generally use the on use trinket in slot 13 for consistency with the same macro.
Ah, I saw that he had listed /use 13 and /use 14 meaning both trinkets at the same time.
I grouped trinket/racials/abilities all into one just to cover all my options. I just pointed out trinkets as being the possible hiccup.
I know I can’t use my racial of Regeneration and some other abilities at the same time due to them having GCD. e.g. I can’t use Last stand and Regeneration at the same time.
I mean, he technically could just do a simple one like Thanos listed without even the need of doing a cast sequence macro.
