RULE CHANGE
You are no longer required to have substitutions. Also, not all of your subs have to play at some point. However, please be aware that there is no change in the rules about stopping. The game doesn't stop except for server failure.
Note about not having subs: If you choose not to have subs, you cannot complain about lagging out. The game doesn't stop for anything. If two of your players lag out and you are stuck in a 1v3 situation, it's your fault for not having subs.
