Help about class quest

Ok so, I want to level an ally resto druid (feral through leveling), and I have a problem with first class quest, I can't kill Lunaclaw, I always do it at level 10-12, and I can't do it, btw when I try it on horde it's lot easier, so any help ? (I'm not using looms)

Self buffs, max rank spells, pre-HoT, use spells you can utilize in the fight.. Entangling roots and heal and so on
