Are you talking primarily for PvP or PvE? If PvP, I'll agree with you; PvE, on the other hand, is a totally different beast - and with Inq now providing crit, we'll probably want to gear more towards haste and mastery.
I wasn't aware of that being the way in which haste affected things, so thank you for that. I'm hesitant to trust the formula there on WoWWiki, as much of the information on that page does not seem to have been made current for Cata, and I wouldn't know where to start with it to make it fit what I'm trying to figure, anyway. But if the same haste that knocks a half a second off from CS knocks, say, three-quarters of a second from Jud, I think that'll still make haste pretty attractive in MoP.
