Now once I hit 8th Circle and got Claw Frenzy I noted it states
Why is Momentum Attack the Beastmaster Discipline talent at 12? It 's explicitly disallowed by Claw Frenzy, an earlier Discipline talent.Claw Frenzy cannot be combined with any talents that allow additional attacks in close or ranged combat, such as Second Attack, Swift Kick, or Momentum Attack.
And If a GM isn't using the Using All Talents To Advance optional rule it's basically a dead talent.
Is this an error? Why isn't Momentum Attack optional instead of discipline?
