Crit's problem is that its rating conversion is determined around specs that function around crits (fire mages, warriors, etc.) because Blizzard wants to avoid the insane scaling that happened with some classes in WoTLK. So if you're a spec that doesn't have a mechanic that boosts the value of crit or requires crit to function properly then haste will be stronger because 1% haste is cheaper than 1% crit.
The best ways to deal with this problem is to add an equivalent mechanic to every spec or just increase the value of crit on specs that don't have a "crit mechanic" like Elemental Fury for Ele Shaman where your crits do more than 200% damage.
