Qzip is right. In yesterday's interview, deej mentioned how light was removed from your base lvl from 1-40. However once you hit 40, light will still again play a part. Its not to define lvls past 40, its about your overall power and all equipment will contribute to your light lvl. Deej also stated that certain endgame activities will be light restricted/recommended He gave an example of something requiring 300 light. To me it sounds like the item lvl system in place in world of warcraft.
