I am honestly not sure why they did not just use the Squadron system for this because this sounds a lot like it just with certain NPCs. If there is nothing more behind that, then they could just have used a new glamour options that turns your squadron into certain NPCs.

In the end this is still a MMO and I am not sure if I like it that they are part of Shadowbringers thus current content. First squadrons still cant go into every dungeon becaue of the mechanics so I kinda wonder if they made it better (and if so why not use it on Squadron?) or if they made dungeons with less mechanics so that even NPCs can go through with it, which would be horrible..

Also what if they are easily unlocked and are better than the random players? Wouldnt a lot of people just use them to run through dungeons? How would this affect the queues?

I can understand squadrons for older stuff, especially for DD players. But for new content? Shouldnt there be 100% enough people trying to do it so that they dont need them?

I will give my final judgement when its in the game, but right now I kinda wonder why we even need that...
