I don't think that the ranking system should change.
All the things you mentioned (game, weight, size, scoring) are part of the challenge. Determining which robot is the best should not be part of that challenge.
The ranking system is actually similar to many other sports or competitions. If you win all your games, you'll be ranked well.
The only small twist that FIRST has is the ranking point system and it main purpose is to distinguish between two team whose records are tied.

Whatever people come up with, the Win/Loss record should always be the biggest determining factor. Having a system that rewards close wins over dominant wins seems contradictory to me. If a robot can shutout its opponents each time it plays, why shouldn't it be ranked #1?

In the eliminations, a win is a win is a win. It doesn't matter if you win by 100 or tie and win by tiebreaker.

Also, if it ain't broke, don't fix it.
