An attempt to organize a team tournament between countries!

Armageddets, what you're suggesting for acceleration is like a disservice; you're trying to force in methods from other disciplines, but it won't work here. Matches will still drag on, people will still disappear and lose motivation—this isn't a 1-2 hour game (especially since this is SoD!). The more people there are, the more drama there is, and as for forcing everyone to stream... I think you've encountered that side of the issue yourself. There's one thing I don't understand: having run a tournament and faced these problems, you're still floating in pink clouds of an idyll woven by your fantasies of a perfect tournament. If a sponsor is investing funds, I think they want to see a quality tournament, not a chaotic mess with players dropping out and throwing feces at each other. Look at what happened in the previous team tournaments and Interportal tournaments + the last World Championship... maybe you'll understand something. It's much simpler, as I already said, to split the tournament, similar to FB OFB: you do qualifiers with all the stuff you've come up with, and then the actual tournament itself, which won't have a ton of people and deadlines squeezed to death with substitutions and other nonsense.
