you kinda tricked people with the topic title. people think you mean b.net gear optimized, even though you wrote that it's a walkthrough.
hdin/summoner is a great combo for a walk, presumably you don't lose out to tele because you'd be walking stuff anyways, unless u planned to have the sorc taxi.
might + summon with amp will roast norm/nm easily. respec to hdin at any time. only phy/magic immunes would give u issues and u could just skip them.
