Just before the release of the Warmind expansion for Destiny 2, Bungie announced that with the release of the 2nd DLC, the lockout system for the raid will change. What does this mean for players?
What is it about? In the current “This Week at Bungie” blog, Bungie shared that with the release of the Warmind DLC, the current loot system in the raid will be modified. A class-based exclusion system for raid loot will now be introduced.
This change affects players who play multiple characters of one class. They will only receive loot with one of these characters. The “double” Guardians will not benefit anymore.
Why is this important? In Destiny, you can only create 3 characters per account. Bungie likely wants to ensure that players play all 3 classes. However, since 2014 and Destiny 1, power gamers have created three Guardians of the same class.
Then they raid with all three characters and trade items among each other to level up particularly fast. This way, they had 3 chances a week for a specific armor drop.

Players who play all 3 classes only had this chance once a week. This has been a problem from the start.
Class Lockout in the Raid – What does it mean?
This is how it has been: Right now, a lockout mechanism is active in the Destiny 2 raid. Players receive loot only on the first weekly raid run of each character. It is pointless to play the raid twice with the same character.

New loot is only available after the next weekly reset. Thus, if you have completed the raid with all characters, further runs are not worth it until the reset.
What will change about the raid rewards? The new system will switch from character lockout to class lockout with the release of DLC II. This means: Players who have multiple characters of one class will receive rewards weekly only on the first raid run with that class.
For a subsequent run with the same class, there will be no rewards anymore – even if it is another character. The same applies to the raid sectors.
So if you have, for example, three Titans, you will only receive raid loot on the first run with the first character. The other two will not get any loot when you run the raid with them.

What does this mean for players? So far, power gamers have played three characters of the same class specifically to get loot faster. This will no longer be possible.
With the release of DLC 2, the maximum level and the power level of the Guardians will increase. At the same time, leveling up the character will become more challenging and require more time.
Raids and the trials are expected to provide the biggest boost to leveling a character in the future. With this change, Bungie prevents players with multiple characters of the same class from leveling up too quickly.
Thus, only the Nightfall rewards and loot from the Trials of the Nine can be effectively used with double characters. Whether and when this mechanic may also be extended to these game modes is not yet known.
Since the release of Destiny 2, “double characters” could not benefit from the rewards of the weekly milestones. Only the first character receives rewards that drop at a higher or the maximum power level. The other characters of the same class do not receive power-level upgrades from the milestones.
What will happen? Probably, starting tomorrow, some people will delete their now almost redundant “double” characters and create a new character of a class they have not played yet.
What do you think of these changes? Do you also play multiple characters of one class?
