During the drafting period, if the teams really need help for draft, its better if they just dont play the competition? Why don't you just draft everyone's hero including the opponents then only play? Are you in such a desperate position to need help from others?

I would like to also comment about the drafting timings. You should just form a rule to limit time during drafting period and definitely without others help(it is unfair!).

the marshall can disqualify the team if they had extra help. they can also be brought upstairs or move to a few shoplots away to draft. actually, that is not really necessary as long as the 3rd party don't say a word. if u let others help u draft, why dont u just put ur friends behind the opponent's pc and shout out loud when there is someone going to kill them. isnt there not much difference at all as u already received help. why not have more help?

spectators can be warned. if they are allowed to watch, they must thus be silent the entire while. when spectators are getting some comments from the marshall, they will learn how to be quiet because when marshalls say something like " can u pls respect the contestants? ". so its obvious the spectators will learn how to shut up and just keep their comments until after the match.
