Bungie you are FAILING your so-called "mental health"/inclusivity business model.
You claim to be inclusive and open to all regardless of skin color/heritage/mental capacity or illness, yet you continue to strive to make -blam!- harder and exclude solo players who some cannot do the Dual Destiny mission due to their anxiety, disabilities, etc. LFG is NOT viable when half the time you will fail due to toxic players kicking you, judging you, screaming at you, and in general NOT BEING GOOD ENOUGH FOR THEM. You cannot sit here and act as if you do so much good if you lie and hide that you lock content behind multiplayer requirements, and of course the Bungie meat sleeves will defend you, because they 'definitely' don't just have a group/clan to call upon, much less your biggest simps; the streamers. Not all, of course, but you cannot sit and ignore that this was a SH!T decision that proves how -blam!- backwards your so called "community focus" model is. QUIT. IGNORING. US.
Stop using people with disabilities as your shield. It's disrespectful to those who actually have them. And those who do have them have been able to complete the quest just fine.
