Eh, the timing of the vote is more simply that I don't see any merit in placing limitations on the timing. After all, I see it being easier to vote as a good thing.
As for the amount of time. Honestly, with 24 hours, we're held to a minimum of three days for each proposition. Three days for each cycle that gives us a turn. There's still Rat's time to process everything, and the time it takes for the next person to notice it's their turn and make their proposal. That's at least 21 days, or three weeks, for a round. So... yeah. I like the idea of being a bit quicker. And it's not like Mafia where dropping out to savour life for a bit will hurt the game and the collective enjoyment thereof. And, if you can vote before the vote phase, then you don't need to worry as much about the tighter window, as you can generally get an idea of how the proposition is going to look before the final 24 hours, and can safely vote before then. I mean, it's not like anyone besides the voter and Rat will know they did it, right?
So, there's my thoughts behind why I'm asking for what I'm asking for.
