I will probably be the only one thinking this but once you get to endgame and want to create a new character you have the story to redo. If you have to rerun the story to get to level 30 on each character you create then why not start it from BoO at level 30, so that the scaling of the NPCs is the same as it was for levels 1-30 but just tweaked for new gear scores.as the new character will most likely be given high end gear picked up from first run through then your new character is similar to how it is on the current PTS where the character is at the base of operation.

Such that your new character is level 30 with weapons/ gear brought in from first run then you have the story to do to get to level 31 or what ever the new cap is . So that the world then has NPC that scale with you from 30 say to 33.

I appreciate that t this is probably impractical but if you have to do the story for each character then why not do it from where left off such that for instance a previous agent has got the BoC fully upgraded and as a new agent you can make benefit of the unlocked skills and talents.

just a random musing - in Defiance once reached endgame could replay the whole story from scratch would something similar be possible..
