Convenience: Legacy Makeover
Requires Level 10
Requires Legacy Level 30
72 Hour cooldown
Summons a droid that allows you to redesign your character's appearance.
Make it an account-wide unlock to summon the droid, but attach a steep fee (~1-2 mil) for each redesign.
I REALLY like this, being able to purchase storage panes that all of my characters SHARE (instead of having to mail items) would be GREAT. Potentially add a bank account system also: you could have two different credit pools, one for the individual character and one that all characters in the legacy share.
Convinience: Legacy cargo storage
Requires Level 50
Requires Legacy Level 25
Cargo storage that keeps items accisible for every legacy character.
