I got 41% haste Claw in NTOV. Sold my 23% haste RBG for 23K and bought this for 8K on the Saryn server in the Bazaar. I had never heard of it before (I must have been at the right place at he right time)and came out way ahead of the game. My AGI needed the help and the extra DEX makes my weps proc a lot more now. I also made 61 around the same time I got this so it may be a combo of the two, but the extra procs are obvious.
I think he was refering to the Average Price: No pricing data tag on this. The fellow wrote that he bought it for 8k, but never submitted it to the database ot there would be pricing data there.
