Yea they are silly but they still apply. The point of this kind of tournament is to determine who is the best Smasher in terms of handling their characters against another without any random elements to be worried about. Just one person against another. That's it. With the hyper competitive kind of people on this board, it is no surprise if we run into someone here who will get beat and say "Well you just won because of that Starman," or "Well if that bomb didn't show up while I was charging my smash attack, I would have won. Thus I am still better than you," or some crap along the same lines. People are way too prideful. By eliminating things that give any particular character an overwhelming advantage and standardize everything, it's much easier to gauge actual skill in character handling and there will be far less reasons for people to whine about losing. That is all.
A tournament must be held by somebody's rules and standards. If you think a tournament should be run with different rules, then hold one yourself. I'm sure other people will enter anyways.
