I've been reading a lot about the problems Frost will be facing in terms of GCD capping with the coming Tier, has anyone considered a swap in Armour and how that would affect the capping issues? I understand that haste after FB GCD is still a marginal increase (Bomb/Orb ticks). However, how does it weigh up in terms of the crit gain. It is possible that we will hit crit cap without the armour help (I haven't seen any BiS lists), but if not, could using MA benefit more, as crit also scales with mastery.
If you disagree, please don't be argumentative about it, simply explain your reasoning and any proof behind it. If you agree, it would be great to hear your thoughts on this.
