I like the OP's idea. But 20-30 mins seems a bit quick on the draw though. When I'm in a strat run (or even in one of Scooby's missions) sometimes it takes a good 20 minutes to get enough people into it. Maybe it would be best at an hour or so. If you're sitting in the tower for an hour, you're afk. Besides taking up a slot in the arena, you're hurting the eny. As for sitting in a gun and spinning it, well, let's take care of the tower flowers first then worry bout the rest.
