You dont need to submit them, we do require morph applications for morphed characters. Generally we're pretty free but we do ask people to look into the nature and lore of things when they go for a char concept, and if they want to say play something powerful, or something with rank (high ranking) Like a Demon Hunter, we do ask that those do the RP to become that way. Demon Hunters are the only rule we have where we do ask for some progression into the class itself, and ask that an actual Demon Hunter player teaches the person wanting to be a demon hunter.
There are other ranks as well like Knight-commander for example we would require rping out, and progressing into, and maybe talking to people like Jole or Zack (Gm & Admin) about how you can work your way up to such.
And then there are things where there isnt much of a way to progress into it, such as Nobles where you could just start off as a noble.
All in all it just depends on you, the type of character you're thinking about playing, and what you wanna do.
