Bungie are refining, and tweaking Destiny to improve the online experience for players. John Hopson the User Research and CRM Lead at Bungie has stated that."This week, we’ve restricted a small number of the most toxic players from matchmaking." The online experience for many are being ruined by these players. So Bungie is taking serious actions to stop these players. They're also telling other online players to report if they see anything like this happen online.
The problem doesn't apply to you if you're a normal online player. The problem will occur if some players have "really gone out of their way to repeatedly cheat their teammates." Bungie are going to take proper action if the players don't behave, and act accordingly.they're going to be banning players as John states here. "If the affected players keep up this behavior after the restrictions lapse, we will apply stronger and (eventually) permanent restrictions on their accounts," and also "We’re watching, and we’re at the ready to take action in many ways to make Destiny better." So if you're just sitting around, and not participating like the rest of the players. Just remember Bungie are watching.
This is one one of the things Bungie will be fixing in the game Destiny. The other issue that will be fixed is making the boss fights easier to complete. For example the one pictured below Valus Ta'Aurc. This boss will become easier to defeat as stated by Bungie production engineer Brenton Woodrow."We reduced Valus Ta'Aurc's health by a third and reduced the Psion Flayers' shields by about 15 percent. We locked these changes after several playtests with the designers and feel that they bring these encounters in line with the rest of the Strikes."
This is going to be good news for players who want to complete raid missions, and defeat these bosses. In the upcoming 1.1.2 version of Destiny, players will find it less nerve racking when the new fixes are implemented.
