Everyone puts far too much emphasis on DPS for a CM/WW build.
I'd rather stand in 4 arcane beams and not flinch on MP10 ubers while getting hit by swing as SNS.
You remove the chance of death, mobs barely move...you steam roll.
You can do both and there is a big difference between 100k and 150k I would wager. At 100k DPS you would need a multiplier of 10x to even reach 1M EDPS. So sheet DPS does matter but not at the expense of EHP IMO.
