Thanks for the response! All characters should be able to be played reasonably within the setting, regardless of their canon power limitations. The way it's explained here is definitely understandable, and all Servant characters will of course have time to establish CR before they find a Master (if they so choose).

Also (for any other Fate/ players who this may affect), this will be the general guideline for how to play Servant characters, but if anyone has a character with different needs OR they want to adjust this guideline in any way, this is totally fine and can be discussed individually or in the Other section of their app!
