Making an interesting Psychic Warrior.

[Person_Man]

Best powers around that level are Hustle, Expansion, Claws of the Beast + Claws of the Vampire or Vampiric Blade, Stomp, Vigor, and Hostile Empathic Transfer. There are other good ones if you want to mine the splat books, but you should be fine without them. Use your feats to pick up a good melee combo or two (and remember that size effects most opposed checks) and you're set.

War Mind for 5 levels might be worth considering, just for Sweeping Strike.

War Mind has it's own power list which doesn't stack with Psy War. So it's actually pretty horrible until ECL 10 when Sweeping Strike kicks in, and he's starting at ECL 5.
