Shazman said:I don't think that close-quarters combat has any prereqs. Even with a good wisdom, the benefits of combat focus and a good cloak of protection, your fighter will still be a sitting duck when it come to will saves at high levels, so Iron Will makes a lot of sense. You also should diversify with some ranged feats such as point blank shot and rapid shot since your mastery of a greatsword will mean nothing against flying or distant opponents.
or take "throw anything" (Complete Warrior) and surprise the heck out of the bad guy 10-20 feet from you when you imbed your greatsword into him (you'll need to get it back though).
