4-3 (current). The goal of this is to have ICs in the game to provide help for the new players, but in some cases I'm not sure that this is actually happening. Also, there are far more new players signing up to play than ICs willing to help, even limiting the newbies to one game at a time.
5-2. Same idea, but the ratio would help the queue. A minor worry here is that one IC could get lynched quickly, and the other could potentially "dominate" the rest of game.
6-1. The minor worry from above becomes a major one, and I think the IC's "teaching" here would be more likely to be biased toward whatever would help that player, rather than the newbies. So I don't think this is an option, and if the ratio is this high might as well just go to...
7-0. Ok, the obvious downside is that there would be no ICs to "help", but do we need them? The mod is by rule experienced, and can field any general questions. We've got various guides and information that could be put together more concisely for reference. And this would greatly simplify the queue. ICs could still be around as late-game replacements, or even possibly in some sort of "advisor" role (though that would have to be thought out carefully).
Well, I think I've made it clear where I'm leaning at the moment. Thoughts?
