Dodge, dodge, doge.
If you can dodge most attacks u wont need high hp, you wont need to heal yourself often and will have more time to aoe. You can learn poison aoe at lvl 10 and start using aoes while questing and you will level up fast. after that go for 2nd aoe, you should get it at lvl 18, then lvl up defensive buffs, finish lvling aoes and at lvl 30 u you rune boss gears with dodge runes and go nuts. But dodge build isn't so good in pvp.
