It's entitled "Answering Destiny: The Taken King's Lingering Questions". They pulled some queries people had and asked Bungie about them.

So, it sounds like level gates gear which has light that directly affects the damage you deal, so it's the same.
So, it sounds like they've increased the amount of drops to ease the difficulty of gaining light, plus it's much more incremental and no longer will there be the huge step between 29 & 30.
Also, sounds like Mark Noseworthy and I both modeled one of our characters after Prince Adam. Great Minds... great minds. ;-)
