I don't consider OTWF to be neither a worthless nor a critical feat.
For melees, Toughness is nice, Power Attack and/or Precision are very useful. Later on (probably at 9 or 12), you will be able to pick up Improved Critical: Slashing (or Piercing) which will increase your damage output quite a bit.
Quicken and Maximize are another option - if you want to increase your self-healing options. I suggest to have a look at this build, which is the same level split you are aiming for:
