you might just be looking at the top few people on the site. If you want to be conqueror, pick a big ass map, go poly 4, and if you are decent enough, you will have a shot. I'm sure Donelladan, Caff and I could all do that. But OMG that sounds like the most boring thing in the world. So let them have their top 5-10. I consider myself a master of most of these maps, but certainly not all maps on all settings. I join a lot of speed games with lucky scrubs and make speed games and then walk away from the comp like a dumb ass
I think if a good multiplayer picks the right time to launch their attack and gets a little lucky, winning 100+ points (assuming 5 opponents, same rank) is a pretty nice haul.
