Is the Nerf JohnGabriel is mentioning live, or is that on the PTR and it's coming? because I would be happy with 5x doing 180k dps single target, if regular dps does 360k.
What that ends up being is 5x180=900 vs 180+360x3=1260, overall only losing 25% damage and gaining so much survive.
If the discrepancy though is coming where the dps will end up being even worse, then may not be worth it.
