2:1 would be my preference. I have dropped most of my characters because the 3:1 has made it impossible to get anything done with super active characters, but 1:1 might be a little too fast for some people, especially with such a fluctuating player base. I've been in this game for well over a year and considering leaving entirely because the 3:1 ratio is just too slow to get anything accomplished.

A poll would be a good way to do this, I agree.
