This may not work for one reason or another, but I'll give it a go... The mechanics for the guilds right now are basically dictatorships(Although, I realize that the definition can be slightly changed with giving permissions.)
By dictatorship I mean that there is one leader who gives people permissions... So even if he gave people full permissions, a guild with an inactive leader is fairly useless.
So, my 'wish' is for there to be different guild types. One perhaps a republic with multiple leaders. Another, a Democracy(I'm not sure if I'm using the right word) where if enough of the members vote it so, the leader can be kicked and another appointed. I also understand that these can technically be done within the guild's RP limits, but would be a nice little addition to mechanics imo.
