Spike traps and RF doesn't work so well anymore...lack of lifesteal means that those facetanking type builds are basically suicide.
Shadow power is still necessary unless you have awesome loh gear.
Vengeance seems like a must have for most builds.
The two builds that I would like to try are Frost Arrow stacked with Frostburns and other cold damage. This looks pretty powerful.
In group play cluster arrow + vengeance seethe for hatred regen looks awesome. spamming cluster bombs whilst melee keep the mobs at bay would be awesome DPS.
Impale/Chakram still bad. they buffed them considerably but still pales in comparison to the new elemental arrow and cluster arrow. They should make a legendary turn chakram (instead of ele arrow) into a hatred generator to promote diversity- then people would consider using it.
