Inna pants max at 100 for dex if you have like AR on them. Since you are already under the 100 dex number on your pants... I'd go that route rather than give up the vit on the cloak.
not sure what AR you wanna work on... you already have like 477 AR .... *shrug*
I run like 250-300 AR and not much issue at all till I get up in the MP8 area. but... game play style is different... more perma gloom with my 1h calamity
Gear is lookin nice though :)
