With the recent closed PTR information on the upcoming expansion and someone leaking it out.
What do you think of everyone be adjusted to lower levels depending on the planet they are on or the heroics they go into? Some are referring it to GW2.
If it cannot be toggled off / on, you will no longer be able to face roll older content for deco or achievements or just for a bit of fun helping out a lower leveled friend.
If it cannot be toggled off I'm not entirely sure I like the idea of being level 65 and scaled back to level 12 just because I went to Tython.
