Lotsa questions:
1: Ranger PrE's work while Main handing a Throwing Axe and offhanding something? Tempest or Deepwood sniper?
2: Is it common for throwing weapons to be bugged? I literally picked up a +3 Flametouched Iron Returning Throwing Axe today with no level requirement.
3: Enhancement feats like, Weapon Spec, Apply to both thrown and Slash? So would they stack for the purpose of damage? Improved Crit as well?
4: TWF Feat's apply?
The idea stem's from the random tidbit's that Dev's have given us about Mod 7. With the Burst changes, people have been wondering how it's possible to achieve 5x crit, as it's not currently possible. The only legitimate answer is that Half-Orcs get a Axe Crit increase, and DWS on a Throwing Axe = x5. Speculation ofcourse, but it's pretty much all people can think of.
Even without that, a Tempest Dual Wielding throwing axe and a Weighted mace ( which should affect your throwing as well )..
