Another question that needs to be answered: Are players still going to be shackled by the Destiny Spheres when they TR? Many players currently hate not being able to start where they want in Epic Destinies. Even more are going to hate being shackled to EDs if ED XP is scrubbed when TRing, especially if they are still going for completionist.
On of the ways getting around the limited choice of EDs is to level up a character in a class that is in the ED that you want so the ED is unlocked before TRing into the class that you want the player to be. For example, playing a Ranger the first life to unlock Shiradi Champion then TRing into an Artificer. However, now it sounds like players must Bond to the ED they want before TRing. In my example, it means players have to stay in the class they don't want (Ranger) for two full EDs before TRing to gain access to the ED they want (Shiradi) before TRing, instead of just TRing at 20 because some points were dumped into the ED you want.
