Is the build currently on your character the one that you are using in PvP? Getaway with bow/SMG and 26 health? As a warlock, I will say that the passiveness by most warlock players does not work well in the mode. Players need to rush together, and attack isolated players and grab the crests in close range. Long range engagements, sitting in a rift behind cover at a bottleneck, just does not work for this mode. I generally have a 40% win rate in the mode, and most of the losses, is because more than half the team is not participating in the play. They sit and wait behind cover for the enemy to come to them down a long lane (which they are not going to do), they are going to take short range engagements, so they can grab the crests, and overwhelm passive players. The overall passiveness that most Warlocks show in supremacy makes it really hard to play as a player who generally understands the mode, because people dont participate. They join the game to sit in their rift rather than get in on the play and push with the rest of the team. Moving with the team, and teamshot is what really wins the games. There are very few 1v1's in the game mode.
