The reason why everyones so fucked off with it all is from Yr1 we've gone from Destiny, Dark Below and House of Wolves as a season pass, to all of a sudden TTK, Festival of The Lost, Sparrow Racing, another FoTL type event and some vague promise of something bigger, all supported by the relentless pushing of silver/MTs
We as a community should absolutely be up in arms about this, we made the game and we could as easily break it

Now, creative director Luke Smith has taken to Twitter to address concerns over the items, saying: "We aren't (nor are we planning) on selling consumables that buff King's Fall drop rates for Silver." It's entirely possible, therefore, that these items are buffs that will organically be found in the world to increase your chances of finding the loot you're after.
But while that addresses concerns around the drop rate buffs, It doesn't touch on the level-boosters. The original level boosting item was handed out to players with The Taken King expansion, so those who wished to play with their friends could do so instantly, but the subclass boost is new.
Luke also said this on GAF

Couple things:
The Valorous/Heuristic/Indomitable Light were Three of Coins-like buffs sold by the Speaker for Motes+Planetary Materials (I honestly don't remember exactly what they cost, [but it was never Silver] I can't keep the entire economy in my head) but for a variety of bug-related reasons they were removed. They were also - as has been pointed out - in the data files before TTK shipped.
Someone PM me when Zoba hasn't talked about TLW for a month (seriously, move on). Clock starts now ;b
