The AI DEFINITELY needs to be fixed. It has the 'mass & rush' mentality which really makes it boring.
The graphics need to have an overhaul. Fans could make better models than those we have in this game at the moment.
The maps need to be MUCH bigger than they currently. I read that they will increase by like 40%, whoopty-doo. They need to increase by like 200% or more, especially considering the size of the ships (especially with the Executor and Eclipse coming in, a 40% increase won't make a big difference with those ships).
