Does anyone know all or any of the spells combos that you can squish into macros for protection warrior?
For protection warrior.
i’m trying to minimize the buttons i have to push and make things simpler.
Check out the warrior guide on wowhead, there you can find a link to the warrior discord “Skyhold” as well.
Yes, GCD (global cooldown) vs off the GCD. So, stand at the dummies and while you’re attacking, try to use any ability. If it triggers the GCD it will cause OTHER abilities to “spin the clock.” If it triggers the GCD (like shield slam and thunderclap) it needs its own button, or at LEAST a /castquence macro to cut down the number of buttons. Things like Avatar, shield wall and last stand, for instance, can be cast without effecting the GCD. For God’s sake bring back heroic strike! 
I have charge and hamstring in the same macro.
I have demo shout and IG in one macro.
