Throwing axes etc also come in bundles now, and those bundles have 10 charges ( so 10x 50 throwing axes vs the 5x 99 of arrows/bolts)
About the crit, I was wondering didn't greensteel used to be keen for throwing weapons? So instead of keen i now get 1d6 bonus crit damage from greensteel.
I'm assuming most of the templates are based on arrows/bolts so applying a keen spell to a template will also only give the 1d6 bonus crit to throwing weapons.
As Cortex said my dex is low chose to get 18 con to get the barbarian bonuses, 25 str and rest in dex. (Ogre btw so started with 22str 14 dex 18 con). Final levels will be 25 barb 5 fighter.
