I have a suggestion for an improve the ranking system for guilds. I'm an r4 in LeW of kingdom 200. I think there should be an r -1 rank, that can only be used by r4/r5 as a way of messing with someone that messed up.
If someone messed up that bad they should get kicked. A rank -1 makes no sense whatsoever. Alternatively you can promote all the "good guys" to rank 2+ and keep the naughty ones at rank 1.
