as said, you hit the breakpoint very fast. You need 35 extra ias with max fanat. This means that with loh, the most popular glove and a 40/15 jewel you are set. Easy as that.
With mb, you already hit /2, I think and this make loh overkill on ias. Really, for strafe, gmb is a good choise.
Wouldn't he need +50 IAS with a Max Fanaticism Faith GMB to reach max fpa with strafe? Not 35?
