Meh, leadership made no difference. If the players do not wish to participate, what can the leaders do? Kick them and eat them? Wait, that would be considered terrible and be shit on for.
When shit hit the fan some of our members didn't step to the plate and that was a key part of our slow descent into losing territory. Wobble picked it up and every one (I think) stepped up their game to contribute.
Don't get me wrong, I know a few who had headaches in TB from trying so hard to get things moving. But in the end you can lead a horse to water but you cannot make it drink.
