I’ve always viewed cliches as tools that are available for writers to use, not things to avoid at all costs. If Jedi, Sith, and Nightsister characters are suddenly things to be avoided because the Disney writers have done them before, then we don’t really have a forum because people enjoy playing those character types. And frankly, there’s nothing wrong with playing the popular archetypes like Jedi, Sith, Nightsisters, Mandos, Etc. It’s all part of the fun of this hobby.
That said, coming from someone who has a bit of experience playing non-cliche characters (I have a military speeder bike pilot and another character who is a zero-G trooper), it can be somewhat difficult to find stories for them, though that could just be an issue on my end. In terms of finding RP, Jedi, Sith, and Mando characters are almost always the safest best!
