Has anyone mapped this out yet?
EDIT: Forgot a build needs a cool name!
Build name: Face-Shooter
8 artificer(Battle Engineer) / 6 rogue(mechanic ) / 6 ranger(DWS)
2x arty feats.
+10m to Sneak Attack and Point Blank Shot range
Intelligence bonus to damage with crossbows
use of Skill Boost to repair a warforged
You'd just carry a repeater for 99% of the time, and just swap for Manyshot - having both back-to-back will let you put out some serious hurt.
You'd have tons of skillpoints to keep your skills maxed
The only ranged feats you'd need to pick up are PS and iPS, which can be done with the 2 bonus artificer feats at 4 and 8.
Extend might be the only worthwhile meta just for rams might and some of the arty infusions, but swapped out later.
HALFLING: Use the healing dragonmarks, along with a feat slot for empower to give a decent self-heal, you've got plenty of feat slots open.
WARFORGED: Artificer and mechanic heals for WF toons.
HUMAN: Extra feat and skill points!
