Other weapons hit harder. However, on a 24 hunter, DW and 30 agi chants, it is the most agility you can get. You also get awesome points for TM a BiS weapon into SF.
OP isn't an F2P. I'm guessing he's trying to play by the f2p rules. if his main has 20k gold and he spends most of his time in the 20-24 bracket, sure it might be worth it.
even if OP was an F2P it still most definitely wouldn't be a waste as you either keep what you find or you vendor it.
