I’m 95% solo and as long as you’re happy to just hit milestones, it’s fine. But unless you have an exotic quest etc to do, there’s nothing to do after milestones until reset (keep in mind I don’t like crucible and I’m not into being ‘challenged’ with raids or prestige nightfall etc, I play to relax and have fun). I use the app LFG for nightfalls if no clan mates about. The strikes in D1 with strike specific loot and chest keys kept me going for ages in between resets. There’s just nothing like that now. Challenge of elders was good. I used LFG for that and it would have been fine with matchmaking. Regular nightfalls would be fine with matchmaking. Raids are too complex for random matchmaking. They need some more activities to do in between for very slow light increases. A challenge of elders type mode, strike specific gear etc. Maybe even a weekly or monthly quest to collect parts of a weapon by doing particular steps each week (as long as they can be done solo or with random matchmaking) and at the end of the month you take those bits to the gunsmith for a special monthly weapon. Just more ‘cool’ things to do for more than just cosmetics.
