The janitor was good fun, but I think he didn't have a thread. The Minion ask thread failed horribly as there was no interest. Don't remember Baron or the shop keepers, unless you mean the shop threads that are up now.
I am not agreeable towards any creep RP, but if you can make the character work, entertain, and make sense...at least IC wise, then I won't yell and scream about it.
My main point is that I want to know if we can have high ranking summoners RPed, be they OC or RC (Riot Characters). Is there some method to do this, cause if we say its allowed and six new people run in saying that they can boss the old OC summoners around, heads will roll.
Someone roleplaying a summoner who is higher up the ladder should be informed that they can't just pop in and tell us to wear a fish for a week or some ****. They also shouldn't be allowed to boss someone around daily.
