i've found that the ahune encounter went much easier for me by using seal of wisdom, moving around a little bit, and casting only divine storm, and consecrate to take out the little waves of adds and for the hailstone big add what i ended up doing was blowing divine shield(the half dmg bubble) and divine sacrifice on my prot pally, then burning it down.

Lol albeit my pallys are more geared than the average it seems, but i've gotten to the point now that i TRY to get hit by the spikes as this way i can farm snowballs (you get pockets full of snow for getting hit by the spikes lol)

i agree with the "dont feel rushed" portion that was stated earlier, the only thing you NEED to do is to kill the hailstone quick and use your defensive cooldowns to survive him, then its all a matter of dancing in consecrate, divine storming, and managing your mana and casting heals whenever you proc an instant heal

@kate, you should totally get yourself the ilvl 245 crafted bracers for your tank! they only cost 8 titansteel bars 20 saronite bars and 4 crusader orbs, and you can save up for all that easily or use a few badges to get them (the orbs). The rest of the mats can be gathered super cheap to make the titansteel

good luck with it all =D
