Let me try to rewrite my post into one cohesive thought. 
-Delete inactive guilds in the system
-Saluki’s idea of maybe limiting guild creation to a certain level like 200.
-Create events that promote guild unity which gives you some kind of bonus. (not materials as we have them now)
-Let Guild Leaders reward their players somehow through something visual or some other bonus. Which would allow them to reward for loyalty. Similar to how on our profiles it tells how long we’ve been in a guild, but it should actually do something in the guild. Kind of like how forum birthdays work now or an “employee of the month,” type of thing.
Once you get to a top-tier position in the guild through promotion, currently there’s no other way for a Guild Leader to show appreciation for a player’s effort and loyalty.
