It's not going to become play to win, Bungie already said that. It's just "cosmetic" items. Stuff like emotes, shaders, emblems maybe. You guys are throwing a fit over nothing. Also, to all the people saying that we should be getting the stuff for free, Bungie also released that we are going to be getting FREE Story Content (Raids?) for the rest of the year until fall of 2016. That's apparently when Destiny 2 will come out. Chill.
It starts out as just cosmetics but then it will turn into things like direct color changes to raid cosmetics we worked for, and selling up to par legendaries
