I don't want to begin to explain how stupid this topic is but to put it in to perspective there are amoeba that could probably think things through better than you have when you decided to write this topic.
Because Ill need to explain why its stupid:
- People don't show up and then replacements can't be found
- Players leaving in the middle of matches (has happened)
- One player being a god and steamrolling all opponents (SirRaZor in our last MoonShade comp is a good example of this)
- What would be the point? fun? prizes? whats the goal of this 5v5?
