Not too sure why this thread has been downvoted to zero... But, as alot of folks are saying here, holding out for Taken King would be the most cost efficient option. As far as your question goes towards the social aspect of the game: Join a clan or find other players through LFG. I promise you Destiny is a much fuller experience when playing with others, and in the reality of non-matchmade endgame content, debatably mandatory. Here's the catch: If you do want to join a clan or play more socially, you may be expected to have your dlc up to date. Destiny is a progressive experience, both in character growth and new content. You should assume that other socially minded Destiny players are keeping up with DLC, and if you want to join them, know that they assume you are keeping up too. Clearly you enjoy this game to go as far as you have since it's launch, even without any dlc. Being on the fence about new content and doing activities with new people is totally understandable. At the end of the day, I guess you need to decide if Destiny is something worth investing into monetarily, because the majority of players who keep playing often will. Hope this helps.

Unless you plan to continue paying for overpriced content I would just play a different game. You need to own both expansions to get TTK. If you're on the fence then make sure you're willing to pay more because you'll have to once the next expansion after TTK/Destiny 2 comes out.

No point of buying destiny if you're not gonna buy the dlc

What system are you on

If you have a physical copy, I would wait for The Legendary Edition, then gift your copy of the base game to a friend. That's one person to play with. In the meantime, give Destiny LFG a try. Maybe for Nightfall Strikes or 32 PoE (this will get you the rest of the way to 34). As you find players that you enjoy playing with, send friend requests.

Maybe not the dark below but HoW and the Taken King for sure.

What console...either way hell yea you'll have a shit ton of fun for awhile
