I would love a ranking by "Control points over used CPU", or filter the rankings by shards (because the CPU limit of shard3 is the same for everybody). I'm trying to optimize my strategy to generate a maximum of Control points by using a minimum of CPU. It would be fun to compete for the most efficient code. Having the "all shards" option would be the same as it is today (so we would not loose any current feature), but filtering only shard3 would put all the players on a equal footing (because of the 20 CPU limit).
