This. This probably not is the full extent of what they can do in destiny. Everything in the Beta is probably not the full list of activities and type of activities.

You realise that this is exactly what a beta is for? For the players to give Bungie some advice on what they like/don't like about the game.

But with it being so close to the release? Pretty sure this is for minor tune ups and network testing, also that still doesn't mean they have to show everything. I thought I remember seeing something about crafting weapons, and that wasn't in the beta, probably because it is something that doesn't really need to be tested before launch. Also things that have similar builds and designs to one another(the free roam missions). They haven't even tested all the PvP game types. Again, I think this beta was just a stress test, mainly.

Bungie have been saying the whole time that they will be adding things over the course of the gamw
