Guild Wars 2

Not sure if this has been asked before but this is not in the wiki. So…

1) Does your gear scale down? How exactly does it scale down?

Does it scale down your gear based on character level or gear level? For example I’m a level 40 character wearing level 20 gear in a level 20 area. Does my gear still scale down?

2) Do the the bonuses given to you by your traits (e.g. plus power or precision) scale down as well?

So… does anyone know?
