But if it does scale the way you want it to, then the power trick will be to do the quests, but never turn one in for completion. This will give you on level Mob Experience, and then the scaled CPs by turning in the quests at a higher level.
Of course this will only work in most side quests, the main quests will still need to have each stage completed (for the most part)
But I have to think that they have thought of this. Although I am leaving content behind on my current character that just got to Coldharbor, and I may roll up another one and have them speed through the zone quests just to have them parked and waiting.
Load up the PTS and a L3 and a VR14 and find out. You will know as soon as you beat Doshia or find the first set of books.
EDIT, just found out that they are doing a character copy tomorrow (or soon) on the NA PTS. So, roll one on the live server and gear them up so you can have an equipped low level character on the PTS.
Not possible since you can only have 25 quests active at one time
