And they offer no additional/unique rewards.
Nightfall has set limitations/boosts and a time limit, whereas the raid can be run at your own “phase” and checkpointed for easy retry at a particular encounter failure. Both of them can be run perfectly fine with matchmaking, there isn’t actually a lot of pre-screening interviews and reading through of CV’s before I pick someone from DTG Discord to do Raid/Nightfall with, I usually just throw my bnet there and invite the first people that add me.
I guess you could argue that a player that uses a 3rd party app/web-site to faciliate playing the game (because the designers are fubar or come from an alternative galaxy where matchmaking and “dungeon finder” hasn’t existed since before some of them were born…) is more likely to be 1. interested in completing the content and 2. competent enough to complete the content, the 2. is never a guarantee and the 1. probably goes for the 1000s of console players who do not have a laptop available to “LFG!”.
BungLe just have one mindboggling design mistake after another, you’d think we were looking at a polar opposite of Star Citizen, where instead of being unable to implement good ideas they are able to implement each and every shitty idea.
