So, here are my suggestions for how to help melee out WITHOUT introducing new systems into the game:

1. Make Stealth Good Again. If you're worried about Invisibility, reduce the duration to 10 seconds per level instead of 1 minute per level. Enough mobs have True Seeing these days that it's much less of an issue, anyway.

2. Make Stat Damage Work Again. It's worthless now, and this should be a valid tactic. You have to whack something a pretty substantial number of times to get anywhere with stat damage under the best of circumstances.

3. Make high AC do what it's SUPPOSED to do. Adjusting the hit calculation formula so that you can actually get to a HIGH chance of being missed instead of, hm, 60% at best. A HIGH chance of being missed is more like 90%. Calculate what the highest possible actual AC is and make that 95% miss chance.

4. Make the epic melee-oriented feats non-awful. There are, what, a couple dozen caster-oriented epic feats now, and WHAT for melee?! Blinding Speed and Overwhelming crit? The epic melee feats are ghastly. Bulwark of Defense is incredibly awful. Suggestions: Epic Stunning Blow. Epic Trip. Epic Sunder. Epic Power Attack. Epic Combat Expertise. Epic Precision. Epic Resilience. Epic Shield Mastery. Wider divergence of options.
