Enh shaman and Tier set stats

why in the world does our own tier set

NOT GIVE US STATS that are important for our class?

I have so much crit that i dont need and very low haste as an ENH shaman because the tier set.

Im positive if they can morph the set bonuses to match a spec, then they shoud be able to morph the sets stats to match what spec we are in, or at least let us choose what stats we want as we equip them
