I've tried searching for this, and have found a few lance threads, but nothing tackling this exactly, so here I am.
I'm making a halfling barbarian (this character), who will be a mounted charger (the thought of that image is enough to make me want to play him). Anyway, so I'm of the opinion that min-maxing chars is ok, as long as you start from a inherently inferior position. :D
Anyway, this is my question - can I use a medium 2-h lance as a one handed weapon on my mount, and thus able to use it as a 2-h weapon on my halfling? In everything I've seen, people point to it not being thematically right, but that doesn't make sense to me, as lances were originally used two handed from horse back. It is kind of stretching the intent of the rules though.
I think it would work, but I just don't know.
