I know, its been a loooong time since I played a first level wizard (or sorcerer) - hence the Toughness feat, I was a bit worried about being downed in one hit in the first (and every) fight. Figured it kind of made sense for a Necromancer too (IIRC they had a high Con score as a requisite in 2nd edition).
I think that character v character conflict can be a very exciting part of the game. But there's a fine line, in almost all cases I find character v character COMBAT (particularly if killing is the intention) to be farily distateful. It usually ruins the game for me a little, unless there is a VERY good in character reason for it, and everyone is mature and respectful about it.
