Challenging PvM classes/builds

[:1]Hi,
I'm looking for some class and skill combo ideas that are challenging in PvM even with epic gear and high level.
Some ideas I have thought of are:
-Sorc with skills in all 3 trees.
-Barbarian with no synergies and points divided into several different attacks.
-Some sort of caster / physical paladin hybrid build like vengeance/foh or hammer/zeal
- Firebow / lightning javelin amazon
Anybody have any suggestions? I have no interest in PvP, I just want a PvM challenge that dosn't involve constantly pressing 1 button. I also want to return to Hell after completing it, and be presented with a challenge, even in full set gear like Tal Rasha or Nats.|||We at Baron's Bazaar have come up with many group challenges that involved things like getting as far as possible in HC with only starting gear, or limited spells (essentially saying you can't use the good ones!)
Good times!|||Use a random number generator to pick three skills, and you MUST take those to level 20 asap. The build will usually end up revolving around some of the less-frequently-used skills.
Spearazon (no lightning :-) )
Naked sorceress.
Barbarian who only uses items with white text (normal, not magic/rare/set unique).
Assassin who only uses one-of-a-kind items (no set/unique).
Bowbarian.
Paladin who only punches (so probably holy shock).
All I can think of (or remember from long ago) for now.|||Any build without CB. And try to do UT.|||Dragoon (aka Leap Attack Barbarian) I plan to try that one out one ladder to take on Diablo Clone as i'm too lazy to collect keys for UT.

get faster cast speed and let your merc tank while you blast it with 400 point heals every .5 seconds
