Speaking as someone who's actually been around for two separate versions
, here's my POV.
1) While there's going to be a lot of turnover from one version to the next (a lot of us who were here for v4 won't be for v5), the thing is... SOTF isn't going to be getting any smaller. There are already new people popping up for the Mini and in preparation for v5, and once pre-game is even hinted at (through a concepts thread or the like), you'll get them coming out of the woodwork and posting their character ideas. Sure, a lot of these characters won't make it to pre-game, let alone the island, but we had an enormous influx of newbies for v4, to the point that it became obvious that the cap would be reached straight away and anyone who was planning to have more than four characters was deluding themselves (yes, once upon a time, people actually had MORE than four characters, and were able to introduce new students during the game itself as their other ones died). And I expect v5 to be pretty much the same. So unless you want 400 students next time, I think that cap limits of less than four characters are going to be a reality.
2) With that said, dropping all the way down to one student per handler just seems wrong to me.
3) Speaking as someone who didn't post responsibly and held other handlers and characters back with his inability to write, I *personally* don't ascribe that to having too many characters to focus on. My not posting was the result of various issues that don't have much to do with my actual ability to post, and moreover, I don't think that other handlers should feel punished because some people didn't get their posts in. Obviously, if people have several characters there are going to be ones they devote more time and development to than others, but that would happen whether they have two characters or two dozen. And having less characters doesn't even mean that you'll like the ones you DO have any more. People have designed characters as their flagships only to kill them off in disgust on day 2, while their supposed fodder characters last until the end.
