I feel this is a great way to prove class sizes are all relevant. By doing exactly what the campaigns of other games did, start you out small, and allow the gameplay to prove itself that they all matter. That this game is different. Sure it means lights get their toy sooner, but heavy class players are used to waiting.
One idea is that if you are a lone wolf you get a medium, but as part of a house you get payed better per mission anyway.
