The only problem that I have with LE Norman Osbourne is the lack of damage reducers on his forst click. Give him Protected (to represent a single click of Impervious) and he's a solid choice.

I too opted for the shield LE ironman, just made sense, well that and the fact i had a second 1 lying around.

We really do need the Dark Avengers in the next set

Maybe LMD too. Norman's dial is not too far from what I'd imagine Iron Patriot to be like sans damage reducers.
