haste on fury is good but theres only so much of 1 stat you can add before you start having to give up to much to push further into it.
and i am a firm believer that haste on ret is a bad stat you have very small burst windows as ret because of the 20 minutes cooldowns and no matter what ammount of haste you stack your burst is still a small window. its better to stack vers/crit and bide time with healing until the right time to go in, and when you do you always kill because youre critting your TV's
ive tested this out in duels, and bgs. that haste is almost always a wasted stat on ret
