I think on the 1st time around it's easy to overlook some of the ancillary warrior skills like shieldcleave, offhand disarm, pierce/thrust/slice, drive etc. There is a lot more in the tool kit than I think an average warrior uses. Exspearamint! (Yes, that's a spear spec joke.)

I'm so cheesy.

ANYWAYS...

I think preps are monumentally important in the hero ranks. At the least get fillets and fly potions. It's also good to have aura and shield if you can as well. If you make good use of all the tools + preps you will do well.
