Sorry to post this a little late.
This is the movie I used to check out this fight when I first did it, its been speeded up and is nice and fast (good for ppl with a short attention span =p)

We dont appear to do anything different than here

intercept at the touch of a button:
#showtooltip intercept
/target al'ar
/cast beserkerstance
/stopcasting
/cast intercept
/stopcasting
/cast Defensivestance
/stopcasting
/cast Bloodrage

basically this should target alar, put u into zerker, use intercept, put u into def stance, and give u rage. but im not sure if it works as ive never tried it yet lol.

(it also shows the tooltip for intercept so u can be sure that alar is in range of the charge before casting)

please note i made this up off the top of my head so i'm not 100% sure that it will work, but i cant see why it wont.

problem is if the tank who is nearest to pick him up is not the one who was tanking him before he went to the middle, there will be a problem of insufficient rage to use intercept.

Other problem is I don't think intercept is in range when standing at the bottom of the ramp- think would need to run quite a way up .
