Armor traits and stacking these?

Raudgrani

I've been thinking of which armor traits are worth stacking, and which ones are really are not.

A couple of examples:
If you have one piece Well Fitted, the dodge roll cost is reduced by 5%, that's fine - but how much is the reduction if you have two, or three or more? It sure isn't another 5% per piece, right?
A trait that I guess is fine stacking is Impenetrable, as it's a flat value, and it seems that it isn't lower the more Impenetrable pieces you wear.

If I'm making a build with Senche's Bite and Eternal Hunt, I'll naturally want to dodge roll every now and then, but it seems to me that like 2 or even 1 piece Well Fitted would sort of do the trick, as it's a Nightblade and I don't wanna focus entirely on dodge rolling, but getting my damage up etc.

So, in short: Which armor traits are worth stacking? I and many other's run in mostly Divines and Infused, and of course it's all about your build and what you mean to do with it. But I mean in general, technically speaking.

the build editor shows well fitted under "item" for how it tallies the cost reduction:
"RollDodgeCost =
((floor(34 + 5.62*EffectiveLevel)*10)*(1 + CP.RollDodgeCost))*(Skill.RollDodgeCost + Item.RollDodgeCost + Set.RollDodgeCost + Buff.RollDodgeCost + 1)"

So it looks like well fitted is additive when gathering all the percentages for item, set, skill and buffs but multiplicative between that, CP and base cost.
