You want the following:
- High spread 6 delay + Shield for Sword & Board
- Epic + 3 second for dual wielding, until you get either of the following:
- 4 second x2 for dual wielding, or
- 6 second x2 for dual wielding
There's a debate between 4 second and 6 second, but either way you don't want your weapons too fast. 3 seconds x2 is as fast as you want, and the only reason to get 3 seconds is to easily pair with the Epic weapon (however there are better weapons than the Epic these days).
You're on the right track, but I would start going down Shadows before going back to the Warrior tree. The AAs there are just much more useful than Warrior Sentinel's Fate stuff (especially Battle Hardening for a soloer).
