if u switch ur secondary to W/Me its really easy. just use Elemental Resistance, Watch Yourself, and Dolyak Sig to reduce damage. Use Heal Sig whenever you HP gets down to about 50-65% then just bring like Eviscerate and other skills for damage. Should work pretty well.
just get any fireydragon sword any sword build change to warroir/mesmer and bring elemental resistence, works, also works for any casters pretty much, and if you need more armour bring dolyak signet and watch yourself
