If you have a 5% Crit buff on your team via ShS Rogue, Fury Warrior, or Feral Druid then Haste becomes better than Crit. If not, then you want to prioritize Crit over Haste. However, both those scenarios are dependent on you being one of, if not the primary, sources of damage on your team. If you are on your team for control while paired with a heavy hitting class, then you want to maximize Haste to reduce your GCD and reduce your Polymorph cast time.
