Agreed. If I took Buster Commodore, resigned from the Rogues, and applied (as Buster) for the Liberty Navy. I would fully expect to be rejected. Hell, I would Expect to get rejected If I was applying for say Blood Dragons as well because of RP and Lore reasons.
But I think it is also fair if someone is rejected on the basis that their character is extremely far-fetched. A character should only be based upon a natural lore. If you have a half goat man applying for your faction then (depending how a leader feels about the subject) should have the say to make a human, nomad, character. however on the RP part of the forum it should be rejected with an RP reason, and then PMed the true reason for rejection OORP. How stupid would it be if I applied to K'Hara as a half woman half cheetah chick, using a picture of Cheetara from Thundercats, and having a character basis that I was a warrior cat lady that flashed forward in time into the Sirius universe from some far away planet and was looking for a place to call home? though that might be ok in some factions, it would not work with K'Hara.
@ Huggie, I think a persons ability to create a completely new character on the fly that would fit with lore and faction ideals is proof enough that a player is worth a damn at RP.
