If I have 2 fighters that both have disruptive do they stack to cause enemy casters to have a +8 to their DC or do they not stack and thus only a +4?
I would say since its the same feat it only applies once, since the feat is the source of the increase, not the fighter.
I agree with Wraithstrike. However, the menacing stance penalty granted by the fighter's brawler archetype (UC page 44) does stack with the effects of Disruptive, IMO. :)
They stack. Disruptive doesn't cause a penalty it increases the DC so you have a penalty combined with a nonpenalty. :)
I would say they do stack. This isn't a bonus, it is an effect, and the effect makes anyone's concentration check 4 higher than it otherwise would be if you threaten them (etc. etc.).
Two people doing that to you makes it 8 higher, 3 makes it 12 higher etc.
Mechanically it is more similar to a penalty then to a bonus, but as it is written it is neither, and there isn't any reason that it wouldn't apply.
If you are within two auras that do damage, you take the damage twice even if the auras are the same thing.

The stacking rules mention effects not stacking. Its not just about numerical bonuses and penalties.

I'm not sure where you get this.
PRD: Stacking refers to the act of adding together bonuses or penalties that apply to one particular check or statistic.
yeah, they seem to both apply, both increase the DC by 4. They aren't a bonus or penalty so it would seem that they'd both work fine.
