Best friggin' idea in the world!

[GooglyBoogly]

If noobs don't get it, and won't listen to others or watch what others are doing, no ammount of features - apart from perhaps having the AI take over control completely is going to fix that. It might be worthwhile to allow the AI to take temporary control of your tank, as long as it cannot sell weapons/items or trade-down the tank. That way newbies can be encouraged to play with the AI on for a few minutes and get a feel for how the game goes without sitting in base the whole time and missing out on xp.
