Prot PVP hamstring macro

So I have never played prot pvp, or even prot warrior for that matter. I have played some casual arms pvp and the standard macro for most people is always charge or intercept together with hamstring.

Now that you can use charge and intercept in defensive stance it gets a little tricky.

So is there a way to add a battle stance switch and hamstring and then a switch back to defensive stance into my current arms macro to make it into a one button charge > battle stance > hamstring > back to def stance macro?

This is my current one:

#showtooltip Charge
/startattack
/cast auto attack [harm]
/cancelaura Hand of protection
/cast [@mouseover, exists, help, nodead] Intervene
/cast [@mouseover, exists, nodead, harm] Charge; Charge
/cast Hamstring

I see. I have made a new keybind for it now.

What is the standard opener?

Charge > concussion blow > devestate > shield block > slam > shockwave ?

There isn't a set rotation, but for optimal damage i d go: charge, devastate, devastate (getting sunder armor, deep wounds and possibly some procs going), concussion blow, devastate (maxed out sunder), disarm (10% more shield slam), shield block, recklessness, shield slam, shockwave, devastate/revenge, sword & board procs on CD and devastate as filler - this is your perfect scenario where you just blow sh1t the fck up honestly if you're BIS or close to it. You rarely have the chance to be as precise (mostly vs melees that don't have a slow), but this is what you should aim for regardless in terms of optimal rotation damage - wise ofcourse. If you wanna be extra cheesy and nerdy you can even try to get a Shattering Throw in there for the armor reduce debuff lol

i would say you don't need hamstring as prot. if you wanna peel go arms. for dps : it goes smth like this :
zerk stance >recklessness>def stance>shield block>battle stance >charge> stun/silence>shield slam. and do that with 100%arp please :-D
