Rimefang's claw is better. If you are a pally mongoose is p good, otherwise I'd say go with blood draining (even for a pally I still think blood draining is better, but since pallies get both better coeffs from agi and better uptime on mongoose it is an acceptable alternative, for a warrior I'd really only go with blood draining since the uptime on mongoose isn't high enough to justify it imo, and bladewarding is actually better avoidance for a warrior (just no armor or crit like mongoose gives, so you have to weigh that).
