Exotic Weapons

[Kriogen]

To be able to use exotic weapons, you have to take a feat. Usually you'd expect that if it costs something it also works better (vs for-free martial weapons). Now, this is not allways the case.

Khopesh: It is better then martial wapons. No need to change. And no, zero need to nerf. Don't touch.

Bastard sword: change its, so you get 150% STR bonus in main-hand, just as it would be 2hander. NOT +10 Power Attack, just STR bonus. No effect if used in off-hand.

Dwarwen Axe: give it x4 critical, so its like Heavy Pick but 'slash'.

Kama: change it so, that you get full STR bonus if used in off-hand. Like Monks handwraps.

Great crossbow: change into x3 critical (or more). Its a slow weapon, but maybe it should hit hard. Like a sniper riffle?

Heavy Repeater: change base damage into 2d8. Scale number of 'bolts per reload' with BAB. 2 at BAB 1, 4 at BAB16+ maybe? Make it like some sort of battle/assault riffle?

Light Repeater: lower reload time. Like some sort of fast sub-machine gun?

i partly agree. however, some of your suggestions are pretty harsh.
bastard sword1.5 strenght modifier can be pretty harsh on a barb or fighter. this would tend to be overpowered with the greensteel version
dwarfen axe is pretty close to kopesh for dwarfs (and they mostly get them for free). no need to make da's more appealing for non dwarfs imo.

you forgot the shuriken btw
