As far as I remember mobs lvl 85 and below won't hit above 1750 hp per swing. I recommend to check before taking the following into consideration.
SK, Clr, mage, druid, RNG, NEC.
Get SK the
Wurmslayer so he won't get any damage if mobs hit for 1750 or less.
Druid for easy transport.
Mage, Ranger and SK himself to cast max Ds after pull and plee has hit all mobs at least once.
NEC for AOE-dmg-orb, instantly fd after the orb is casted, so he will not get any damage on his count.
Clr for occasional heal/rezz if things did not went as they should have. NB: no reverse Ds from cleric, as it's damage will count for the cleric.
Use ds-pl Methode.
SK clicks off all ds and runs off to grab a nice amount of mobs. Be careful to avoid ripostes as much as possible while pulling. Once back in camp be careful to turn the SKs back to all mobs, easiest to be done, if there is a corner the sk can run to.
Cast the SKs PbAoe-aggro at least once, when all mobs arrived. Attn to use the PbAoe with unlimited targets, not all fall into this category.
Once Aoe-aggro applied, hit all mob once with the plee.
Than cast all ds you can apply on the sk.
If you want the mobs to die faster, cast the AOE-dmg-orb with the nec and fd instantly.
Now sit sk until all mobs are dead.
Rinse and repeat.
That way all XP is applied to the plee.
