OMG I see I submited your bog standard reply even on first words! And here I was thinking that part is gonna give you so many variables it's gonna be absolutely useless. What surprised me is most people are happy with the party of 4 and RTWP bunch being in such minority. Good job!
Let's nuance things a bit about party size. More than 40% is not really such a minority. It means than 4 players out of 10 aren't satisfied. Not that the 60 other % wouldn't enjoy 1 (or more) slots.
About TB yea, I was one of the most dissapointed at the beginning but I love many TB games and I've made up my mind.
