This forum has poll functionality. It seems like it'd be vastly superior to do that instead of asking for individual comments in support of/against.
E.g., select all you'd be in favor of: - Allow up to 6 with no additional changes - Allow up to 6 but with changes (e.g., split exp, rebalancing encounters, default party size, etc) - Allow more than 6 - Keep party limit at 4 - Reduce party size below 4
(If you do create a poll, it's probably worth iterating on these options a few times with other posters to create a somewhat "official/approved" poll)
