In an interview, lead designer Virgil Watkins mentioned that the developers were considering a special mode or raid that would require the use of the best gear:
We've discussed many different criteria for queues. Of course, there are examples like the labs in Escape from Tarkov, where you need a special item.
However, he noted the potential risks:
At the moment, we don't want to segment the community too much. We don't want to put people in a situation where they say, "I want to play with you, but I don't have the required item, so we can't play together."
Such a mode would likely turn predominantly into PvP, which could deter PvE enthusiasts. Watkins emphasized that the idea is not ruled out, but its implementation would require a cautious approach.
