IF you have similar gear to what I have, more points into BoS isn't going to do much...

Level 25 BoS is what I should have with 1 point. That's 54% IAS. Now, say you put in 10 more points. What do you gain? 2% IAS and something like 3% r/w. That gets a BIG 'woot'.

I would use those skill points on something useful.
