I am slightly concerned by the rendering of monsters into simply combat stats. Please take this opportunity to allay my fears, as much of what I hear, I approve of.
Will there be more to monsters than combat? Obviously, that's their most important role, but an understanding of their capabilities outside of combat (rituals they can cast, things they know - stuff that they WON'T use in a fight against PCs) is important to give a monster an ecology, purpose, traction - to use a popular word.
Please explain to me how 4e takes account of this, or if it doesn't, explain why you have designed it thusly.
(Oh, and thanks for your time and effort. It can't be easy redesigning D&D, what with the internet and all.)
