SMN and Carbuncles
Just add 2 Job spells that allow summoning of upgraded Carbuncles (that have equal potency to the Egis). Problem solved.

You can add the whole glamour system later when you have the new Egis ready.
DRK and Aura
So many complaints about this. Give players the option to turn off it's display - even if it's done via a slash command.

Something like this could be implemented in a hotfix.
But nope, they drag it on and on and on.

Just patch in these quick fixes and be done with it. You can "do it right" when you have the time or save it for next expansion.

How are people suppose to play the game when they aren't even happy with their character?
