I agree with deans last two posts, weather would be a nice detail in forge. I think it would add a nice new change of pace, imagine playing infection in low vis fog, or juggernaut on his aforementioned post with ice.
I remember reading in another forum about forge skins, this could be an idea for one of them. I like choices, i don't like being forced to be one thing or the other.
I think Pelicans and Phantoms are the largest vehicles we should have in forge (except elephants) realistically, Scarabs and frigates would be awesome but its way too out there. Locust in replace of scarabs would be more reasonable.
