We hear alot of people say level is not imporant to them. Since that is the case perhaps we should elminate the leveling system entirely and let guilds buy whatever ships and buffs they want. That would be a good way for Turbine to monetize the guild system without a heavy investment. There will always be new people that want to start a new guild and are willing to buy astral shards to do so. I have been playing Star Wars some with the guildy that left ddo and there are no advantages at all given to players based on their guild. I like that system much better.
Perhaps require "time served" for ship requirements rather than net renown based on a broken system.
