I dislike munchkins.
You character should always be well thought of, or you'll have no bond with it what so ever. That doesn't mean is should be weak though, even in combat.
A sneaking character can be powerfull if played well.
Avoid combats, take the roleplaying way and backstab, dubblecross or whatever instead.
Make a nuce background and create a powerfull character to go with it.
However, talk your DM into trying non-combat problems! Climb down a wall while the tower is burning down on you... see how the munchkins do with all their skillpoints in combat skills. You have climb points though and make it down easily.
Or, instead of your DM doing this in his campain... run your own and do it yourself. Give another point of view, they may like it.
