Oh I am. It's not exactly the same. For one thing it's not a map pickup. You just need ammo. Also, you can block with it as you approach so there were multiple instances where I was dumping into a dude and he just shrugged it off then one shot me. I'd also say the attack pattern of the halo sword was more predictable. There was a certain lunge to it you could anticipate. Haven't picked up anything like that on this sword yet. Hopefully I will.
The Halo sword didn't let you lunge forward freely to move quicker on the map. That's what I hate about the sword in PvP.
