What do you use to manage endurance on your Widow? My Night widow is absolutely sucking wind after going hard for 30 seconds. I don't have the build but trying to come up with one. Does anyone have a good comprehensive plan for keeping that blue bar from getting to empty? I'm trying to build a Melee focused, Mostly single target, Widow, and there are a lot of options to help with the blue bar just not sure which is the most efficient.
