Look at the playerbase. There is problem. Players are leaving, matchmaking is taking longer, clans are vanishing and your response is to alienate the casual players who may go on to joining clans and filling out your fireteams. If your response to these players getting into the game is 'Go play something else' then this game is going to die. If casual players are encouraged to log into Destiny 2 and they enjoy the single player experience they may join your clan. Its a question of balance. Provide options for solo players while maintaining a challenge for fireteams. Fireteams pub stomping solo players in Quickplay is not balance / being excluded from activites which don't really need communication is not balance. Raids do need communication and should be LFG / Fireteam only.
