Charge macro

I got a small problem. Due to no GCD i'm charging out of combat, meanwhile stancing to berserker stance and using intercept aswell ending up with no mobility if i spam that macro:

#show [combat] Intercept; Charge
/cast [nocombat,stance:1] Charge; [combat,stance:3] Intercept; [nocombat,nostance:1] Battle Stance; [combat,nostance:3] Berserker Stance
/console cameradistancemaxfactor 50
/startattack
/cast Bloodrage
/cast Hamstring

Anyone has an idea how to improve it, not to end up with intercept on cooldown?

I use two macros. One for charge and one for intercept:

/cast charge
/cast battle stance
/equip gorehowl
/cast [flyable] Cenarion War Hippogryph; Reins of the Black War Tiger

Last line is optional but I use it to dismount. I think there's an addon that does it too.

/cast intercept
/cast berserker stance
/equip gorehowl

Hamstring and bloodrage are also separate macros but I dont see why you couldn't add those. And max camera distance can be set in settings. But I don't have any keys left to bind so combining them can be good. I might put hamstring with my intercept actually.
