If Warriers don’t get BP but we do and both sides on 21pts, then how is seeding then decided - points difference or tries scored?

(c) If ranking remains unresolved and/or if clubs have not played each other previously in the pool stage, qualification/ranking will be determined as follows:
(i) the best aggregate points difference from the pool stage; or
(ii) if equal, the number of tries scored in the pool stage; or
(iii) if equal, the club with the fewest number of players suspended under Disciplinary Rules in the pool stage; or
(iv) if unresolved, by drawing lots.
