It can hit enemies on different elevations, or behind cover, or in different rooms. If you have 109 and max all the appropriate skills, you can hit the dodge cap, but nice round numbers appeal me more than putting one more stat point into something else. A shotgun master using Glaive Sweep triggers the stun and blind effects easily, and if your weapon has a chance to trigger a spell when it hits, this also applies to Glaive Sweep. You can also blow up your own brambles to trigger Poison Burst, which is handy if you’re using Venomous Hail. I've been trying to develop a good character build for the outlander class. One way to deal with this is to socket the Rift Ember you get early in Act 2 that gives 10 mana steal on hit. It hits for half of your weapon’s listed damage per shot (not DPS) at rank 1 so shotguns get the most out of it.
