I totally agree with you.
The argument against Standard BRs (and I don't agree with it, but it should be presented) is that it produces radical point swings. There is a fear that this could be abused. I won a Standard BR, and I believe I jumped from Lieutenant to Colonel. I wasn't particularly trying to gain points; I was just happy to finally win a BR. Still, there is a belief that someone who knew they were about to win a Standard BR could reduce their rank, and then suddenly jump 2500 points or more.
My answer to that is, "So what?" Even setting aside how lucky you would have to be in packing the game with high-ranking opponents to gain a jump like that, still, "So what?" Why is jumping 2500 points in one day so much more dangerous than jumping 2500 points in six months? (And doing the math, a point gain of 965 points like I had is vastly more likely than the hypothetical 2500 point jumper.)
Still, it's one of those things, like the idea that a resign button would lead to indiscriminate point dumping, that was written into CC lore early on and is very hard to overcome. Still, it can be done, with patience. There was a time when all BRs were freestyle. When I first suggested Sequential BRs, I was told I was a retard, that a Sequential BR would take hundreds of years to finish and was a completely absurd idea. Then, after much campaigning, the powers that be agreed to try a Sequential BR for
Game 10000000, and (miracle of miracles!) it was over in ten weeks, not a hundred years.
Since then, Sequential BRs have become commonplace, and I don't know how many people even remember the days when proponents of the idea openly had their sanity questioned. I don't think there's any inherent reason why we can't have Assassin BRs, or Dubs BRs, or anything else. It only requires a groundswell behind the idea. Upping Standard BRs from the current 10% of the mix to, for instance, 35% of the mix, is not nearly as radical as those other ideas, so with a bit of hustle you should be able to sell it.
