Scythes are my only real issue, everything else is pretty well balanced. PLS remove the ftr/wm only restrictions and the better scythes (Khamul/Isenmouthe Captain) could stand to be siginificantly better, especially Khamul's.
One of my favored builds is 29cleric/10cot/1monk. Max ab with might/shield and the other good stuff is about 66! No wm levels in that and the 5-6 builds that are actually better are well...better
Regardless though, khamul has the 2nd best scythe, its 2d6 elec/acid. The best scythe is +2, keen, 2d10 elec and requires a caster to make it +5. That has no comparison to the top 3 best great sword/axes....not even close. It costs a feat, it should be better.
1 handed weapons I don't care so much about as they should be considerably weaker. Though I do think Stormlord should be better than the standard axe drop besides just the keen. Keep in mind I'd still never use it.
Good suggestions can go a very long way as long as they are feasible.
