Anyone else planning on starting a new campaign when White March Pt. 1 drops? If so, do you plan on doing the expansion content first, or scaling it up to end-game level and saving it for last? (In an E3 interview, Sawyer mentioned that it would be an either-or, determined by an in-game prompt that kicks in if you enter the new zone at a high enough level. Literally something like "you are probably going to breeze through this content, level-12 Watcher, want to scale it up?")
I know with the 2.0 changes I'll want to start a new run, and I'm tempted to save the expansion content for last, because I've already had enough issues leveling too fast during the main campaign. (Thanks for resolving those, IE mod!) Still, I'm hoping it's possible to enter PoE snow zone right after Act 1, grab the two new characters, take them along for all that Watcher vs. masked dude business, and then return to finish off the expansion content and have it still scale up to 12-14.
So I guess what I'm saying is in an ideal world, you could start off with unscaled White March content, and still choose to scale it up if you come back later at high level.
