Right now the heavy blade zaw is what everyone is carrying for conclave. It seems to be glitched as in it has a much wider arc and range for the air attack than the animation actually displays and does upwards of 300 damage. People just grab an iron skin Rhino or Nidus and have a near unkillable one-shot load out. I'd hope they outright remove zaws from pvp, I just watched a whole lobby of hammer-zaw players team on a MR2 Volt with a skana and take turns teabagging the guy. That's just another player who will never come back to Conclave.
