Gear one out with lichen shield guard, felsteel spike, vengeance card and high block value. What we found worked well was to let a dps warrior/rogue follow the one hatcher kill it immediately after one egg and solo kill that one hatcher. On the other side, someone else is tasked with killing the hatcher after 3 or 4 eggs. stand on the main platform by the bridge, thrunderclap as the adds appear, ask for a slowing trap if possible and frost novas. As long as you hold agro for a decent length of time it work's ok - can be kinda messy.
Most important is for everyone to spread out, as you dont want squishies with fire de-buff getting hit by the bosses' fire thing. Even if a mage pulls agro off all the hatchers currently up, they won't kill him the fire debuff will.
We also tried a holy pally tanking, it worked well except it meant that we were low on healers, but I know people who use this strategy.
