Bungie have activated Destiny 2's week-long even that provides a ton of new rewards and more importantly, a way to cut through the 950 to 960 Power grinding slog via Iron Banner rewards.
Destiny 2 services have slowed down to a crawl and that's because every veteran is rushing into the game to start farming Iron Banner gear and get themselves up to 950 or 960 Power easier, provided they hit the previous soft caps. Lord Saladin can be found in The Tower and he provides Pinnacle Weapon rewards for the players who wish to progress through Power levels faster.
That is, if you are willing to play the Iron Banner version of Crucible. It is basically the same as the regular Control mode where players are battling and trying to hold more control points in a 6v6 match. There are a few twists though.
Iron Banner mode enables Power advantages, meaning those with the higher number will be more powerful, which is usually not the case in Destiny 2 PvP.
The second major difference from the regular Crucible is that Power Play is replaced by The Hunt. If you are new to Crucible entirely, Power Play / The Hunt refers to the situation when one team captures all three control zones. When The Hunt activates, those zones will remain locked for 20 seconds for the team that captured them, allowing them to freely pursue opposing team's players instead of focusing on objectives.
In a nutshell, if a team happens to be slightly ahead, The Hunt will make sure they get even more advantage, as opposed to regular Crucible's Power Play that allows the losing team more chances to come back.
Anyway, in order to be able to purchase anything from Saladin, you will need to complete the Pursuit he will initially give you. Fortunately, you will get Pinnacle Weapon rewards each time you beat a step of the pursuit, on top of the regular Iron Banner Crucible rewards.
