Guild Wars 2

Hey there,

I recently found back to Guild Wars and now with my Mesmer being 80 for some time, the question how to equip her stands before me.

I’m currently running a Staff/ Scepter + Focus build focusing on conditions and shattering.
Here’s the build so I don’t have to explain everything, I guess it’s pretty standard:

Currently, I’m wearing the lvl80 Tailor Masterwork Carrion set but as I looked for a Exotic Set, there are two possible options:

1. The Tailor Exotic Carrion Set (Cond. dmg > Power = Vitality)
2. Khilbron’s Set (Cond. dmg > Precision = Toughness)

Basically, the Khilbron set is the same as Arah/ TA/ CM/ HoW set with Cond. dmg as main stat, but looks significantly better and is ‘buyable’ for gold.
Another substitute would be some of the Orr Karma sets, which have the same stats.

Now, assuming I would take 5 points out of Illusions trait line (no more Phantasmal Haste) and put it into Chaos to get Chaotic Transference would this be enough to compensate the loss of DPS due to weaker Shatters because there is no Power on this set and my Mesmer almost doesn’t benefit from Precision.

Or, to put the question more easily: Which set will give me more DPS, Khilbron or Exotic Carrion?

Also, another question:
If I take 6x Superior Rune of the Undead along with speccing into Chaotic Transference, will I get both bonuses (aka 10% of Toughness —> Cond.dmg instead of 5%)?

I’d be glad for any advice, expirience reports or general input you can give me.
Thanks in advance.
