The weapon tuning 2.0 nerfs. Probably Bungies plan all along. All year one weapons will be weaker and obsolete, once “The Taken King” DLC drops. The DLC will of course introduce a whole new set of year two weapons having higher attack values. Players will likely not be allowed to ascend any, legendary or exotic, year one weapons to the new, year two attack level. IMO, this is why Bungie has been virtually silent on this matter. They have seen the backlash in the forums where many players are not happy with the idea. Players have vowed that they would be done with Destiny, especially if they quite literally have to start all over again. Well welcome to phase one of this being done. The primary reason for this update 2.0 is to make all of your favorite year one weapons, not so great anymore. Of course there are other valid reasons for the update as well. However, they are pretty much nerfing weapons across the board, even ones that didn't need it. All things considered, I believe the primary under lying goal is to ease players into the changes that TTK will bring without turning them off to the idea of buying it. Bungie is hoping the nerfs will make your year one weapons less desirable, it will then be easier for them to separate you from these favorite weapons and make TTK a little more appealing than it would have been, had they not done this. Destiny lacks content, so they want to reset progress and make players grind out everything all over again, with a tad more content at a hefty price. Many are ok with that and say it is expected from games like this. Others are not ok with it. Either way, Bungie should just fully disclose what their plans are and reveal in detail, exactly what new content players will be getting for their $40.
