I've never experienced a Great Lance. What exactly is the problem to it? Does it happen to, say, be of a energy make? Like light sabres from Star Wars.

Otherwise an argument about the technological advancement of arms and armor is teh dumb. When I think of great lance I imagine a jousting lance wholly of steel with a needle point instead of a four pronged head.
Lances were never (afaik) made wholly of steel. I would imagine mainly because of the weight issues of carrying them around. I think when jousting was required, most lances were actually cut on the spot from local trees, resulting in some, sometimes, strange lances (think about a lance made of a springy, lighter wood, vs oak for instance).
I could be wrong, however, since little of my experience with lances is based on historical fact.
