Not too much to the rotation. I use a few macros to have less buttons to hit. With a PowerAura for when Deadly Calm is up for 10 seconds, I go through the rotation while holding shift too for the free HS.
Code:
#showtooltip Mortal Strike
/targetenemy [noexists][dead][help]
/startattack
/cast [combat]Sweeping Strikes
/cast [combat]Deadly Calm
/cast Mortal Strike
/cast [mod:shift]Heroic Strike
Code:
#showtooltip
/targetenemy [noexists][dead][help]
/startattack
/cast Overpower
/cast [mod:shift]Heroic Strike
Code:
#showtooltip
/targetenemy [noexists][dead][help]
/startattack
/cast Colossus Smash
/cast [mod:shift]Heroic Strike
Code:
#showtooltip
/startattack
/cast Bladestorm
