Am i the only inf/arc??

I actually was an inf/arc (3/2) hybrid before 4.0. It's a versatile style, although you're not much use as a shielder in the shield wall, you're kind of relegated to being a slasher or another archer if there are too many commandos. You'll see a lot more Xbow/Inf or Inf/Xbow since Xbow gives a better gain on melee stats than the archer tree does.
