Seriously considering Asc. Celestial Armor
My posts are facts as I know them, or my own opinion, and do not represent any guild.
Ascended armor stats are
Major: 329
Minor: 235
Celestial: 156
Trinkets carry nearly double the stats. I’m not sure you would notice the difference tbh. Is 156 in the lesser stats really worth it to you over the loss of nearly another 200 mainstat AND another 100 from your 2 secondaries?
I run full celestial gear on my condi warrior but of coarse keep sigil of corruption and condi dmg infusions. It feels good since I can use ALL of the stats.
Celestial gear would seem more like a crutch for a thief. Class has a high skill cap and I would recommend switching back your trinkets. Don’t let a little death discourage you ;-)
