I don't think much has changed in the percentage of good sticks vs bad sticks. The pyramid still looks the same, it's just a much bigger pyramid due to a much larger player base and a constant influx of new players combined with the burnout rate of older players.
It's harder for the "elite" to dominate just because of the pure numbers of people online. When there were 100 players total in the arena, you knew who everyone was and there wasn't a sufficient enough gang to counterbalance certain players abilities. Now at peak times that isn't the case.
However, in the mid or early war maps, or in the lw in off times, those certain players can and do dominate the newer or less skilled player quite easily.
