Everyone who is saying to not change anything, doesn't even tower, or supports the easy way to 1k. I haven't towered with an active guild for maybe 2 years, because it's too boring.
Recruit nubs, take tower, gives nubs powers to recruit, let them do the work, kick all nubs in the morning, repeat process. There needs to be a punishement for kicking people. That way people will recruit wisely. Maybe their friends, or just skilled players.
