If you are very skilful: Solo players can get Luna & Recluse. Nightfall’s can be soloed. Same as Zero Hour, Whisper, Thorn. The only thing that can’t be soloed are raids. I am not that good, I used to play solo and used to think like you but because I really wanted to do Nightfalls and Raids and some quest I used this app and also joined a clan. There are some very nice guardians, and playing with others is so different than playing solo. It can be lots of fun plus one can learn so much. Think sports, it is very different solo sports like martial arts or boxing to team sports like basketball or football. Team needs communication, different rolls, strategy, etc. Team activities are not just about shooting adds. It is a complete different dimension. Give it a try you will be surprised, or just become better and then you can solo most things.
