There's a pretty huge difference between "unoptimized" and "completely worthless." Unfortunately, most melee builds with 10 strength generally fall under the latter.
...And the ones that don't generally need a scootch more dexterity than 13. But crisis averted, stats could be moved around. Decent melee power is within reach.
I made the sheet for the guy public if you want to continue critiquing though. I welcome any and all (constructive) criticism!
Just as a quick head's up though, I'm tempted to make him a Str, Dex, Int oriented character utilizing a high AC to deal with attacks rather than a high Constitution. Thoughts on that idea?
Since Duskblades can wear heavier armor and don't get a penalty to their spellcasting for it, you'll probably only get use out of a few points of your dex mod. A reach weapon would help in keeping enemies from getting into range to hit you, but even if you were to use one, you really can't afford to neglect your Con.
