After some thinking i'm going to go falcata
if my math is right(and please do check it)if i use a falcata
as a regular specialized fighter the falcata has the same crit rate
but higher damage especially if combine with a burst enchantment
falcata lvl 20:
Str 36, greater weapon specialization, power attack, weapon training 4
+5 weapon
20(BAB)+13(str)+4(GWS)+4(weapon training)+5(weapon)-6(power attack)=+40
Hasted attacks as +41/+41/+36/+31/+26
these hit 95%/95%/95%/80%/55% of the time respectively
dealing 1d8+13+4+12+4+5= 1d8+1d6+38 dmg per hit plus 3d10 on a crit
with improved Crit and Weapon Mastery we are looking at a
17-20/x4 crit or a .6 crit rate
Scimitar lvl 20
Str 36, greater weapon specialization, power attack, weapon training 4
+5 weapon
20(BAB)+13(str)+4(GWS)+4(weapon training)+5(weapon)-6(power attack)=+40
Hasted attacks as +41/+41/+36/+31/+26
these hit 95%/95%/95%/80%/55% of the time respectively
dealing 1d8+13+4+12+4+5= 2d6+38 dmg per hit plus 2d10 on a crit
ith improved Crit and Weapon Mastery we are looking at a
15-20/x3 or a crit rate of .6
this is unless someone can come up with a single feat that would be more beneficial to have
