The primary difference between this game and a "MOBA" (man do I prefer the term ARTS), is that it's completely asymmetrical.
In an ARTS/MOBA game, BOTH sides would have a giant orbital cannon and a base. Here we have an attack/defend scenario, which plays differently, but could still be balanced using elements from the MOBA genre.
Maybe if they actually did create AI tanks or something, we could give the players "creeps". It'd be interesting, at least.
