Spawn locations in villain warehouse maps
It's not only that, but the "Front, Middle, and Back" options for those maps are all terribly wonky. Things need to be straightened out really bad in that sense. Nothing spawned near where it was supposed to, and I ended up having to use a hero warehouse instead.

They're just plain bad. Check out this screenshot I took of what I'm talking about. You've got a crate and a superadine lab sitting practically right on top of each other. In that mission I've got a lab and 3 crates to protect, and 4 allies. Hardly any of the objectives spawn by themselves. A crate, for instance, pretty much would always have another defendable object or an ally right next to it. Not only does it make them spawn inside of each other sometimes, like above, but especially in the case of the defendable objects the two spawns together would be absurd.
