Which means the classes with access to the combo (WD/Wiz/Monk) will have a higher chance of winning.
(I'm also considering a DPS RF DH with vengeance as primary DPS but I don't really know if it will be on par with a Skorn CoB WD in terms of cost effectiveness)
Because they won't need to gear LS or LOH.
Why? 0 Dog globe heals. I'm estimating at least 40k per globe bonus which is cheap on armor.
Primary DPS (WD) will be running 1300-1400 skorn with 500 int and 200 vit (costs less than 100m for a snipe) and will be running CoB with Gruesome Feast. Globes will get 50% extra int, which will boost the tals and zunis that he'll be wearing.
Monk Will spec IAS based SW cyclone dps and resource generation for overawe spam.
Wiz will spec IAS CM for lockdowns and DPS.
Secondary WD will be running 0 Dog setup with IAS for cast speed.
Each class will be at 450-500 AR 4-5k armor and 60-70k life (minimum survivability)
Having not to gear for LOH and LS greatly reduces the cost of each setup, allowing them to spec for DPS multipliers and cheap weapons.
Oh and both WD's have the possibility of running minions which increases party survivability as well as a slam dance for damage spikes (they can rotate slam dances meaning 40 second of bonus for every uber fight and major boss fight)
