jamoecw, I have to vote against Pillage and Shieldwall as you've written them. Pillage seems a micromanagment hell for limited gain, and Shieldwall is grossly overpowered as long as it gives your level in AC. That's a giant bonus once things get up even a few levels, and it's pretty much free because most infantry will probably already be moving at medium load speed, on the grounds that most infantry have better then light armor.
I do think a javelin using unit sounds good for the ranged unit though.. I'd prefer to call him the Impaler however. Sounds cooler then the Skirmisher in my opinion.
Could you explain how this works? Most units already will have more then one figure in them, each with their own attack, and you seem to be claiming that a unit with two figures getting two attacks is special, which it isn't, so I feel like I'm missing your point..
(As well as the fact that most infantry would have four figures in their unit, so something with two figures doesn't sound that powerful anyway..)
