you mentioned robots which could transport zombies and other creatures from underwater worlds and other planets to other places. but how this zombies will be produced? turians, asari etc needs to be transported from colonies to one planet, yeah? (reminds me humans abductions by collectors), to turn them into zombies ( like in Sanctuary but without technologies in bodies). just one factroy or many? cuz this factories can be easily found. ( just tracking down the robots after abductions of any colonists)

About servant race. doesn't matter how they will look like. the main idea, is that this servants must be like Rachni. cuz when you control the queen - you will control millions of her workers, who actually will be ready to die for her. simply.

this Great One suppose to be strong but don't make from him a god ( we already have one god in ME3). he can't control all robots,servants,zombies at the same time. plus he need to care about resources and things like that. actually he needs allies, y'know. And these allies MUST not to be indoctrinated by Leviathans ( cuz in ME1 we already got Saren, so no more references to original trilogy) so these allies should have their own reason to help Leviathans.
