Mercurio way to go!

I tried him again this week and got him to 40% but I still can't get him down. Right now I am just using 2 priests for healing so I think I might respec my boomkin or shammy to see if its easier with 3 healers.

Did you use the same positioning as theradin?

How were you handling taking down the bone spikes?
I setup a separate macro to /target bone and then have all my dps cast fast nukes and that seems to be working ok but if a healer gets bone spiked its almost always a wipe.
