During yesterday's Star Wars: The Old Republic live stream of Knights of the Fallen Empire, Bioware's Eric Musco revealed that planets will be level synched. Players going to low- or lower-level planets will have their levels scaled to match. The forums are aflame with players letting developers know in no uncertain terms (overall) that this is an unwanted feature (go here and here for a couple of examples), though in fairness, there are big supporters as well.
The discussion in the stream video below begins at about 1:43:00 so you can judge for yourself.
Do you think level synching is a good idea for SWTOR? Leave us your thoughts in the comments.
