It's been a big debate here about how crit is getting better and better as your gear improves and as you get haste. Currently, some shamans (hi Finnober) value crit as better than haste, when you get to astronomic values of haste (let's say 1300+ raid buffed). And that increasing your crit will get you more damage on the long run, especially if you have the anub25 trinket, heroic or not.
My opinion (remember, still not Truth©) is that you'll maybe gain a very bit of dps (thanks to the +sp/+haste you'd benefit), as I believe the stats you'd gain are worth losing what you'd lose (err a bit weird sentence, sorry, english is still not my mother language).
