Yep. This is also because I'm not sure we'll reach 14 people in any reasonable amount of time. We've got six at the moment, enough for masters. While Alice's goal is very good, and something I'd like to explore sometime, this isn't the best forum to do so. Instead, the plan is we'll make everyone a Servant and a Master... but not their own master Servant pair.
As is I'll be taking sheet submissions for every class, along with making my own. I'm hoping to get at least 35 servants, 5 from every class. I'll basically from there do a hero roullete style thing. This way, we get a large variety of possibilities, and makes the actual servant selection something you have to guess at... though I'll throw in a group of artifacts to select from if you so wish to take one and not trust your destiny to fate's fickle rolls.
