How do you expect Bungie to fund this game? Seriously, they have to get money somehow, how do you reason the funds it takes to make the content we play? Do you even understand how much it cost to make TTK? Microtransaction profits are used to make new content in lots of different games, to name a few, Mass Effect 3, GTA V, Warframe, ESO, Path of Exile, Guild Wars, World of Warcraft... The list goes on.
