Honestly, I don't really mind the TLK roleplayers. We all (mostly) roleplay. No one seems to have a problem with the warriors. No one seems to have a problem with the Horses. Why have a problem with TLK?
My only issue is the abuse of it. Like earlier people mentioned, the repeated characters and people fighting over them.. But also people making random 'daughters of Kovu' or 'sons of Simba' or whatever... Especially without clearing it with the character first... A random cub popping up? Its a bit awkward. The way they abuse being in TLK roleplays bothers me, but overall, I can live with it.
