I dont understand your goal with that macro. Why are you macroing that many abilities together? You need to sync cds and create burst windows as big as you can otherwise you lose a lot of dps. Also ghoul can be used as a defensive sometimes since is reduces all damage the target does to you by 15%.
I recommend to you to used mod keys then: #showtooltip #show
/cast [nomod] Pillar of frost
/use [mod:ctrl] 14
/cast [mod:shift] Raise Dead
/cast [mod:alt] Empower Rune Weapon
Basically the macro will change the ability depending on the mod key that you press (e.g. if you press ctrl it will use your trinket). I still think it is better to have different keybinds for this stuff cuz having everything in the same button might be super clunky.
