EXTEND SPELL [METAMAGIC]
GREATER TWO WEAPON FIGHTING [GENERAL]
These feats don't do anything.
Extend spell doesn't make short spells last long enough, and long spells already last long enough that they dont need to be extended
Greater two weapon - sheesh when going up a feat chain, you are trying to get to BETTER feats, not one that does LESS than the feat before it in the chain.
Improved Two weapon = 1 extra attack at -7 (at best)
Greater Two weapon = 1 extra attack at -12 (again at best)
