After reading about this, what I understand is that BUFFS with different runes can stack, but EE and CB are debuffs and that will only get REFRESHED and not stacked when another party member applies that same debuff. Just like Monk's Mantra of Conviction, it's a debuff and it won't stack with other monks. That's why EE and CB don't stack and make's no sense to have them as passives for all your chars in the party. Have EE in 1 char, CB in 1 and that's it.
There seems to be very few debuffs that can actually stack and basically just from items (Strongarms, Gem of Efficacious Toxin, etc.). Are u sure WD debuffs stack??? IE: Barb hits a mob and does X damage. WD1 casts Haunt Poisoned Spirit on that mob and applies the 20% damage debuff. Same Barb hits the mob and does X + Y damage cause of the debuff. WD2 casts Haunt Poisoned Spirit on the same mob and applies 20% additive damage debuff. The Barb hits the same mob and does X + Z (where Z > Y) because the 2 WD debuffs stacked???
That seems very strong IMO, even if the debuffs are additive and not multiplicative, that's a TON of %damage.
