Alright, I know this topic has been suggested before, but all of those threads are over a year old at least, and I didn't want to bump an ancient thread.
The title says it all: The ability for Guild Leaders to appoint Deputies
I have been in both member and leader positions in guilds, and I think that having the option to appoint a deputy would be invaluable. Though it's thankfully been a relatively uncommon experience for myself, there are some players that you just need to show the door---you know which ones I'm talking about.
There is nothing more disappointing to log on, only to see that your guildmates require assistance that only you as the leader can provide, even though there were plenty of people online that could have taken care of the problem already.
I'm sure there are plenty of other reasons that other users have cited in their posts. (I'm a bit too lazy to go and paste some here at the moment, however. So I'll see about adding them in later)
Ideally, Guild leaders would be able to appoint a player as Deputy. They would probably be required to be at an Initiated/Regular ranking within the guild.
They would have the ability to either kick players outright, or if it needed to be more balanced, would simply mute the player in chat until it could be discussed with the leader, who would get final say.
