Get rid of the seeding system
Seriously, why does this even exist? It's like giving tax cuts to the filthy rich. If you are a good player, you will get far in tournaments anyways. An unseeded players way to the title will always be harder than a seeded players way.
I suggest we do this completely at random from now on. So what if we occasionally have a Nole-Rafa R1 at Roland Garros or a Fed-Murray R2 at Wimbledon. Equal chances for everyone!
This idea has pluses and minuses. For instance, completely random can lead to the Top 4 exterminating each other in the first two rounds, and only one triumphing. The rest of the tournament would be boring since this guy would take out all opposition blindfolded. So, there will be only a maximum of 8 matches with Top 4 players in them, the rest of 119 will have no Top 4. Since this would be uninteresting, attendance would drop, people would not care, etc.
On the other hand, there's too many seeds to speak of. A decrease in the number of seeds would lead to more interesting matches during the earlier rounds, increasing quality.
