It should be improved.
And Simon there's no way for them to make it do it only applies to tower guilds. Maybe make it so the half hour limit isnt there for when the guild has just been made.
Plus with the chill guilds why would you need to recruit more often then half a hour?
This is the only way to stop temping and noob recruiting. Guilds are supposed to be for your friends, not just the noobs near the tower.
