But doing it that way will tend to make haste look worthless, which it isn't.

Second, the changes to talents in 3.0.2 mean that you need different weightings for Disc and Holy priests. Pre-3.0.2, you could probably get by with one set of weightings that covered Holy and hybrid Disc/Holy, and assume that deep Discipline was purely a PvP spec. Now that's no longer the case.

Anyway, some more specific criticisms of your weights; I'll assume you have a deep holy spec since you mention using CoH.

- valuing mp5 three times as high as spirit is probably wrong. If you assume that you are never outside the 5-second rule during a fight, this value might be about right (though spirit also gets you some spellpower, with Spiritual Guidance); however most models of a long fight assume you can get some OO5SR regen (like 15%; sometimes I assume 20%), and in this case mp5 is only worth maybe 5/3 as much as spirit.
- Int is pretty good. With Replenishment and changes to Shadowfiend, it's as good as spirit even for a deep Holy spec, and much better for Disc priests. People also sometimes forget just how much having a big mana pool to start with will help you.

Valuing spellpower at 1/6 as much as mp5 is low. It's worth about 1/4 as much as mp5 just considering total throughput in endurance healing - roughly, 1 mp5 will let you heal another 720 health in 5 minutes, while 1 spellpower will give you an extra 180. And it may be worth tweaking it a little higher given that it also helps your burst throughput.

So I would use the following weights:
MP5 - 8
Int - 5
Spi -5
Crit - 6 (I have no idea whether this makes sense, I haven't analyzed its value post-3.0.2; just following your preference here)
Spellpower - 2
Stamina - 2 (you can't neglect this stat totally, you will be a soap bubble)

Leaving haste off entirely is probably about the same as setting it to 1. I am not sure how I would weight it, but you should keep in mind that it also helps the global cooldown - so using a lot of instants does not necessarily make it worth less.
