1: hunters go for staves/2-handers and they have options.
2: Shaman hate haste now.

Warriors can get much better options than that.

The set sucks for everyone and it is far too reminiscent of the crap in hyjal where fist weapons that were designed to match shaman gear were better for rogues.

Why are there ANY 1 handed agility swords now?
Axes and fit weapons would be useable by 2 classes instead of 1 fir those swords.

The weapon set would've been so much more desired if it had the "increases by whichever secondary stat is the highest" that way the tradeoff for using some strength would be a 1k increase in mastery which would....wait *droooools*.

Obviously the fact that they picked haste as the set bonus pretty much killed it for enhancers. Right now I'm running a Claw of torment/maimgor's bite setup which is working very well.

When it comes to the actual value of the stats, they aren't really overbudget. Agility and Strength tend to come in at about three times the value of non-hit/expertise secondary stats, and this holds roughly true for all classes. At about 18% uptime, this comes in at the equivalent of 180 haste. When you add together 180 haste and 146 strength, the value of this is less than the 146 agility you'd have from an equal ilvl weapon.

It's like swapping a quarter for a nickel and a dime. You have more coins, but less money.
