During registration, I think a very detailed description of time availability should be required.
For example, I can't guarantee 100% availability on specific days of the week. But I'm sure I could dedicate 2 days a week, from 8 PM to 9 PM Moscow time, to this tournament. And I don't understand... Is it even possible to participate in this tournament with such constraints? Doubts are still lingering.
Maybe you could explain how you envision solving the time problem.
And regarding the maps – how many hours of gameplay do they typically offer (obviously, it varies, but what's the standard)? Or are they all different in this regard?
