[Dev] Does "% increase all damage to target" have a cap?

With proliferation of items with effects like this:
http://u.eq2wire.com/item/index/371787832

that "increase all incoming damage to mob by 0.8%", and stack from multiple (potentially 24) people in raid, we need to know if there is an cap on how high the %increase can go. Can some dev please look up the skirt of the mechanics code responsible for it

related: if there is a hard cap, do the AA skills with incoming dmg-increase contribute to the same cap or on a separate cap (for example, Resist Break for Necromancer under Dragon tree)

thanx in advance!

bump?
this should be on every raider's mind this xpac

what do you mean "this xpac"? Genra' ears (ToV).... Highhold ears (AoM, ToT)

I'm aware of how far this goes however, i do mean "this xpac" because it's more relevant this xpac...

whatever the (presumed) cap was put in place when Dragon AAs and Genra ears came out, it's likely to have been tailored only with those things in mind because it was literally just 1 item for devs to consider. this xpac the "% incoming" items are ubiquitous, easily reaching ~2x the values of ToV days in raid without trying hard even. it wouldn't surprise me what-so-ever if that cap was completely forgotten about when all these new items were introduced.

so, this xpac i have significantly less confidence that all the additional "% incoming" items are actually doing anything useful. or rather this xpac i care because it's now a very likely reality.

without any easy way to reliably reverse-engineer the cap, i'd simply like to have the value told to us, so we can gear more intelligently as a raid.

No declare, No cap.

That is a terrible way to look at these mechanics.

It'd be certainly foolish to assume that, but i sense sarcasm in original

Regardless... we need dev answer puaaaese

i see you lurking gninja! masses need enlightment

pretty please, need cap info

*bump*
come on @gninja i know you want to lift this weight off your shoulders
*uses jedi mind trick* "this is the secret you want to disclose."

It's not even restricted to items. Mages have an ability in their Dragon tree called Resist Break that does the same thing, but it's focused on a particular type of damage.

from OP:
related: if there is a hard cap, do the AA skills with incoming dmg-increase contribute to the same cap or on a separate cap (for example, Resist Break for Necromancer under Dragon tree)

*bump* again, for the coveted dev attention.

I would really like a Dev answer on this, it's a pretty important mechanic that has zero commentary from Developers so far.

My understanding, the cap is one effect per "type", per encounter.

So on one encounter (group or raid) you can only have 1 active of each effect. So it makes no sense past one person having the effect.

I appreciate the answer, but what gives you that impression? Was there a post about it? What is your understanding based on?

Seeing no difference in testing between 1 and 6 effects.

Ok, so what you're saying is that you've tested "Noxious Rending" (for instance) stacking with itself. Your tests say it does not, which is a nice starting point.

Did you test interaction of various named effects, for instance Noxious Rending and Anguish? There are numerous effects of this nature that are in question. I think that's really what folks are hoping to get an answer for. For instance, is there a 10% cap on overall damage increase? We don't know, but there are many, many effects out there that could, in combination, exceed a theoretical cap of 10%.
