Well, if you don't have the time to play, simply don't join the tournament. I know it's rough, but what's the point in playing if you can't play normaly and need xyz days to play a turn? It's even kinda unfair towards your opponent. If you're going to play a tournament, you must be willing to invest some time in it, otherwise just play normaly.
Then again I might be biased, since I also play a RTS where one game is usually about 15 min long and the tournament does not last very long - shorter than a whole day. (if you're eliminated eariler, it's even less long) There the people that can't play it simply don't sign up for it, or if they do and don't show up, their opponent gets a free win.
My other point is that, you can't satisfy all the players, we just need to see what is ok for most of them. I know it's unfair, but that's how the world works. :P We'll need to cast some votes at some time, if we don't find a solution that's suitable.
This brainstormim is good, something should come out of it, I'm sure. :)
grabageonly, that's a good point about stalling, and I think judges would not solve the problem completely, though it could help. But we'd definately need judges, like JimmyMethod said. They should be some people outside the tournament, some neutral people?
We could organize two types of tournaments, speed macromage for the people that have time to play (it might be good to organize groups by time zones or something? but that may be unfair), and normal tournaments for people that don't have much time to play.
People are usually free on saturdays-sundays, maybe allow people to play during the week, but the main play time would be the weekend?
