Mechanar question - 5 pallies

[Jubber]

Make sure your tank has a minor run speed increase enchant on his boots. rest of your paladins should have 2 pts in pursuit of justice. aggro with your tank and strafe backwards with her in tow and the rest of your pallies. Make sure you spam follow on your toons as melee will break follow.

The fire elementals aren't all that fast and they tend to stop and hellfire often. So occasionally they will reach your team but then stop when they hellfire so it gives your team time to move away while dps'ing the boss.
