He's dead on. When I get ready to use arc blade. I wait till I get near a heavy traffic area. Pop, then just go on the hunt till I find my prey. Snuffing 1 person after another.(the thing auto targets so well I can just dive in with reckless abandon)I will always get at least 2 kills, and normally 3-5. On my Titan, i usually just use it to save my ass. Cause if I wait till there is a group, first off, I'll probably get killed just trying to use it against a big group, or, I'll end up never using it cause it's not like I can find 3-4 guys just sitting around waiting for me to kill them. Very few spots exist to truly flank a group with it anywhere. Control sometimes, but again, jumping up in the air in front of 4 guys usually leads to my death before I even hit the button.

Waaaahh I don't know how to keep distance waaaaaah

Watch this video,it sums up everything.
