The build I put up there earlier is basically don't buy any chc gear at all, focus on dex, crit damage, then all defensive attributes, this lets you last longer.
Focus on dropping caltrops either in groups of 4 to 6 or 1 at a time, usually use sentry for 1 or 2 creature groups.
get a large group to chase you, vault into the middle drop sentry + 3 caltrops, stink bomb out, you'll kill most things and sentry eats the stragglers
the crucial thing is focusing on 0 crit chance...
currently working on a no crit all dex build focused on sentry doing all damage and buying very defensive, rather inexpensive gear, i'll keep you guys posted
