'There should be no single answer for how to win in Destiny' says Bungie

Bungie have explained about the tweaks and updates the game receives periodically

After releasing the updates and tweaks, Bungie have explained to fans and players why these gameplay balances are necessary for the game. After releasing the Hotfix 1.0.2.2 update, Bungie have changed the way Destiny handles the shooting, Auto-rifles have received 2 percent debuff, Scout rifles 6 percent damage increase, and the legendary Exotic Mythoclast became balanced.

Bungie have released in their weekly update news about the details of the weapons and how the players are able to use the auto-rifles over longer ranges without any problem. They said,

The Auto Rifle archetype is designed to appeal to players who like to throw up a wall of bullets and not worry if a few miss their target. It is intended to inflict sustained damage at close to medium range, but to lose effectiveness at longer ranges.Today the Auto Rifle is too effective at long range, even beating Scout and Pulse Rifles in some circumstances. Expect stability and/or damage adjustments to the Auto Rifle to address this in the weeks ahead

They also explained why the Scout rifle damage increase was increased by 6 percent ,

Scout Rifles are for players who like to keep their enemies at medium range and hate to miss. They are intended to be an awkward weapon to use at close range but to be dominant - as long as you land your shots - at medium and longer ranges.Scouts just aren't hitting hard enough today when compared to other precision weapons. We'll be addressing this soon

Bungie also said that the players who faced the hardest challenges in Vault of Glass should be rewarded with a weapon (Mythoclast) that stands at the top compared to others and have also stressed that this weapon should not be a to-go weapon always and should be used as a choice in the multiplayer PVP,

You braved our hardest challenges, we want to reward you with a weapon that outperforms the other primaries in your PVE arsenal (Nightfall Burn and Epic Skulls notwithstanding).Mythoclast should be a valid choice in PVP, but should not be the optimal choice. This aligns it with our philosophy on Exotics throughout the rest of the game. We don’t want any one Exotic to be the only answer to the question “what should I bring into PVP.

Bungie also revealed about many of the fixes in the update , like for instance where the players have taken the raid boss Atheon over a ledge to knock out is a bug and is fixed, they said,

We've added 'baby bumpers' to areas where players could knock Atheon out of the environment. Knocking a boss off a ledge is a bug. We will seek to address bugs like these as quickly as possible.
