Hand a Half Training is really interesting. I suspect we'll see the current Juggernaut 16 Artificer/2 Monk/2 Ranger build move from THF to TWF, dual wielding Bastard Swords/Dwarven Axes. The Exotic Weapon Prof isn't even needed since you don't get glancing blows when dual wielding, and the -4 to hit is offset by the +4 hit from Hand and Half Training. You also have the option of dipping into Tempest for +2 hit/dmg, 10 PRR, Sprint Boost and 3[W] melee bleed.
Bastard Swords/Dwarven Axes is now a bonus feat option for Artificers.
