Dexterity is on Ring 1, and Intelligence can go on the trinket instead of Concentration. Though no insightful for either, so yeah, not quite ideal for a dex or int build. Still pretty good, though. Good thought about doubleshot for ranged. Also ranged alacrity on gloves.
I've now crafted almost* all the "Old:" items and stored them on my mule, plus located / acquired almost all the augment slot base items I'll need for the "New:" stuff. Unfortunately, yellow augment base items are getting tough to find; there's still one or two I'm missing. (Something like the second boots and fourth ring, I think.)
*BTA helmets are brutal to farm. Red Fens doesn't appear to drop them, so now I'm eyeing up the various chains trying to figure out which will be quickest. I'm thinking Seal of STK. Ugh.
EDIT: First try blasting through STK on an epic alt I had completion times of 6.5, 5.5 and 4.5 minutes for a total of 16.5 minutes to do the entire chain. I could probably get that down to 13 minutes or so. Unfortunately, this was apparently my third completion so I got all named items, no lootgen, in the chain reward. Doh!
EDIT 2: Second run took 5.5, 4.5 and 2.5 (!) minutes, so already under the 13 minute estimate. Plus I got me a fancy BTA lootgen hat, woohoo! Invisi-sprinting for 12 solid minutes is about as unfun as farming gets, but oh well. Strictly speaking I only need 1 more hat, though 2 more would be preferred.
