I’ve been experimenting with macros, sequences and stuff. And in most part they might be beneficial sometimes, at the same time, sometimes they are iffy and unreliable and jam up. so i try to avoid using them. some /cast spells can be doubled up, which is good and simplifies things. macros can save action bar space and key presses. and save you a difficult reach.
i swap spells for my own and see how they react, seem iffy.
/castsequence [@focustarget,harm,group:raid]reset=combat/5 Exorcism, Crusader Strike, Crusader Strike, Crusader Strike, Shield of the Righteous;reset=target Exorcism, Crusader Strike, Crusader Strike, Crusader Strike, Shield of the Righteous
