For new(ish!) players I certainly suggest Warfare + Dream (= Harbinger). As mentioned before, it's a class that's pretty damn hard to screw up. I find its gear dependency is low, especially compared to a Juggernaut (Warfare + Earth) and Thane (Warfare + Storm).

I never tried a Spellbinder yet, but I hear many good things about it!

If you don't plan on installing Immortal Throne, and thus Dream is not an option for you, go with Warfare and Defense (= Conquerer). It's fairly easy to chop through to the end of Legendary with a Conquerer, and it's very good farming class to boot! Of course this means you'll be able to better deck out your new characters, and help those oddball, off-the-hook type classes through TitanQuest easier.
