Horde Mode

I have a suggestion for a new PvE mode called "Cleaning up the Streets" or "Night Patrol" or something. It's basically a like a horde mode. It works like the repeatable missions do, but it would exist in the prologue as its own section. Basically, it's a repeatable mission that gets harder every time you play it. It could be a good place to mine ISO and HP. Since it gets harder and harder, the return on investment would get less and less until you leveled up your characters more. It can also have progression rewards like the shield training. It will give people some PvE to grind when they are done with the prologue, and there isn't a hero tournament going on. Plus, since it is only progression based, it would reward skill without getting dragged down by other people attacking.
