You have become better at socializing! (3)
No, honestly, I like the idea of some sort of reward for maxing out your character, although I don't think a rebirth system is very feasible. A few options I could picture working:
+1 hp or mana per AA beyond max (I suppose this could get unbalancing)
+x number of fame points per AA beyond max
A whole new set of epic quests, available only to those with maxed AAs, that have more steps and further upgrades open up as you get more AAs. Probably something similar to the MQ in that it'd go step by step with an aug or two that improve as you progress through the quest(s).
An alternate to the fame point system.
Personally, I think a new set of commands for maxed characters would be pretty cool. Give them Legendary Character points or something like that, 5 per AA beyond max. You can spend your points with /cm legendary pointbuy, with a variety of options. A few ideas for them:
-Titles
-Illusion clickies
-Mounts (might be too much of a pain in the ass from the programming side)
-Charm credits, if those ever go in (see Zhak's thread on sale prices of charms, and the option of turning them in for credit toward another charm)
-Access to a fun zone, early Plane of Mischief style.
-Various utility clickies or commands. E.g:
*One that will cast succor (self or group) in any zone in which you can bind, with a fast cast time.
*One that will give you a burst of something like Selo's, but which goes off if you get attacked or attack, much like spirit of scale.
*One that casts invis.
*One that casts IVU.
*One that casts levitation.
*One that casts EB.
I think that something like that would be a good way of benefitting maxed out characters, without significantly altering game balance. They're all convenience stuff. It's not like zipping quickly across an outdoor zone, whether with Selo's-type run speed or with an evac clicky, is going to cause someone with max AAs to miss out on content they haven't seen before. It would be a convenience reward for players who have earned it.
Possibly more ideas later =)
