If you're a solo player you basically can't complete the Leviathan raid even if you have 1/2 friends who play the game. Then Destiny releases Trials of Osiris which in theory should be great but yet again if you play solo its a no from the Devs. So much content locked behind the requirement of having a full fireteam with no option to matchmake. I get Trials etc requires good teamwork but if you're matchmaking you accept you may get a bad team mate so why not let the players decide? tl/dr Destiny devs seem like they don't give a shit about solo players
