Oh definitely. I think it added about 15k true DPS. Swapped Sharpshooter with engineering for the sentrys. Just need to upgrade gems, upgarde quiver with more % damage for Hunger Arrow and should be pretty solid.
After wasting most of my Sunday on battle.net, I think it's safe to say I'm back on the wagon.
This is my gear so far. I think I'm going to try to upgrade the gloves first, then maybe the shoulders/bracers. Spent about 400k trying to craft dex gloves, but I'm giving up and just saving gold to buy a set on the AH.
