I guess we should have a given timeline of 2 hours if the game could not be finish and how the game would be decided if the timeline reaches. (ie: Points? Barracks? Hero Kills and so on)

From the rules given in lowyat.net, there is no such rule stating that 2 hours the game will be over. So, it's possible to let the participants know about this rule before the game starts. Some games could be draggy.

Drafting Heroes Timeline Rule. As mention from Anonymous1234, this rule should be enforced. (Ie: 30 seconds per hero)

Maybe you guys could have let 2 spectators to spectate the team they came cheering for. So its 2 spectators per team.

I guess thats about it.
