Delays between casts

Hi all,

just wondering…
I’m trying to get my brews on my brew master monk automated so I made a nice macro for it

/castsequence reset=combat Ironskin Brew, Ironskin Brew,Ironskin Brew,Purifying Brew

and back in my days as multiboxer without GSE this used to work. ticking spell then using the comma’s as delays then next spell. but for some reason this wont work in GSE.

Am I doing something wrong or us there another ways to “build -in” these delays?
