Item Scaling to level of character?
You get both, if you mean Gear and such. Loot bags off mobs will be zone-level. Champ bags would be both. Chests would be character-level.
Both, but mostly equipment scaled to your level. I just open all my champ bags on a lvl 55 char for linen/rugged leather. I still get lvl 80 exotics doing this, though I miss out on the rares which are scaled down (so what I mean is no ectos from the rares).
