If you're asking if you need to be an expert in the Nasuverse, or fate series then no. However I'm aiming for a heavy team cohesion in this. Servants, and masters will be taking the place of the 'offensive team' in this case our team black to besiege team red controlled by the Grey Family. Statistics don't play a heavy roll but you can't expect a C class servant to smash through an A class servant if they have A Strength. Some servants are immune to servants below a certain stat I.E Heracles with god's hand but he's banned because he's fucking disgusting in terms of power. 

In other words skills, statistics, and skills otherwise will play a good role in it but they won't be the end all be all. Diarmuid from Zero handled Artoria pretty well despite being generally outclassed stat wise his skill of Knight Tactics playing heavily into that despite Saber's B intuition which saved her from Kojiro in Stay/Night. And yes they will be in the Cs in their own section. The wiki has information on there that I should have in the OOC if we have enough people. Or you can go there on your own and research there.

The main plot is heavily centered on the war personal arcs, and stories can be told around it but we're primarily there to dethrone the Grey Family. 

If you're willing to play the role of Saber I expect you to know what you're doing, and be committed. Saber is a top class, and needs to have skill. Mordred is strong, and tough and while I would avoid using her in this specific setting due to her standoff nature, and the fact that she doesn't work well in forced teams she is viable. Saber needs to be able to handle Saber of Red who is top tier in this setting, I can't give his name because that is spoilers but he is one tough son of gun and will be the 'boss' servant so to speak for Red. 

I.E: Saber needs someone who will stay in this rp, be committed, know how to handle the role, and be willing to be the upfront fighter. Someone like Giles De Rais saber for example will get his shit kicked in.

Edit: If someone wants an example of what to expect from a servant here's the servant sheet I will be using though it will be as an example, and not blank. I am not definitively using Rider this is just an example. This Rider is a rather upper middle tier servant being essentially a weaker Iskander in some ways. What would push Godfrey here into OP status would be a better personal weapon, and a reality marble that put him in a territory that suited him better.
