I can upload the save and you can go try it out if you really want to.
dont worry m8, i'm over my high deffense warrior. i will guess i did to little dps to do it like you did, anyway im playing an archer now
Actually I also started an archer in high difficulty, but still just level 5. Bit lazy now to move on, but I guess archer will be more fun, as has more active skill and aoe skills to spam over warrior. In term of defensive, I think it wont differ much by class by end game when fully equipped. Maybe there will be damage difference, which affected mainly by weapon.
