Oh yes need to take Weapon Specialization (WS) on fighter level 4 and then Epic Weapon Focus (EWF) and Epic Weapon Specialization (EWS) on level 21 since EWS requires EWF as a pre-req. I moved Lightning Reflexes out to level 30-something to fit it in.
But otherwise - very nice. Level 43, 118 AC in a pretty haphazard gear set-up and mob bursting damage output.
In a stealth update last night, mighty rage will no longer work if you do not have 21 con by level 60, and demigod stats will not fix it. So it is now recommended to drop 2 str for 2 con at levels 4 and 8. Existing builds will have to reincarnate.
