First game used- 30 kills for the entire game between Bastion, my grenades, and my super. Second game used- 19 kills total in a map where it's at a disadvantage. Bastion is fantastic, but requires you to play in a way you normally wouldn't in PvP. Instead of running and gunning, you need to hang back and carefully choose your engagements. It's not a 1vTeam weapon, it's a 1v1 AMAZING weapon. One burst+Melee kills a striker titan in super. So, give it a shot if you haven't yet, and don't give up on it if you're not IMMEDIATELY amazing.
