Proving grounds tanking (silver) troubles

I can do 1-6 waves like a breeze but when it gets to 7 the Flamecaller plus Wind-Guard just does way too much damage for me to handle, am I not geared enough or should I be able to do it. Here's my character http://eu.battle.net/wow/en/character/emerald-dream/Zarxus/advanced

interupt the flame caller as much as you can, don't forget to AMS, sometimes you can take less damage by kiting the wind guard. also if you havne't used it yet you can use Army.

The general strat I used for those waves was to let the Flame Callers finish their very first cast which is the channel that puts all the fire on the ground. At that point I would use Asphyxiate on the Flame Caller and get aggro on the Wind Guard. Pop AMS and run through the fire on the ground. By doing so it'll cause the Wind guard to run through the fire as well which will cause him to be damaged significantly; by now the Flame caller will no longer be stunned. I would usually grip him to me at this point and cleave him+the wind guard down. Hope this helps.
