I see a lot of people offer different solutions in regards to needing a better matchmaking system in Destiny. I do agree with that an upgrade would be appealing however you CAN solo everything in Destiny except the Raid obviously. I play everything on the highest survivable difficulty and completing them solo is a reward in itself. Weeklies, dailies, queens mission, nightfall, and even level 26 strike on Summoning Pitts to get Thorn. All you have to do is know your enemy, bring the right damage type, and take it slow. Never panic and skip parts that you can. So if you can't find friends at that moment, try to take the journey alone and come out a champion.
