Yep bungie claims this is a social game yet you have to go out of your way with 3rd party sites to be social

I always put no mic required and minimum power requirements for activities to get more people who may not play with anyone to join. Any talking is done through messages because some people honestly would rather just play and communicate through emotes and messages. If clan members are on then a party is created, but we've been going since vanilla Destiny and the bonds are strong. I'm from the UK and everyone else is from the U.S. but we all share the same goal...play till our eyes bleed until we get the loot.

PC, Xbox, or PS4?

Hmm. Maybe you should look into joining a clan? Don't play Destiny alone, it's just like drinking alone. Lol. Destiny is a social game for me. I have a hard time playing it without friends. Start sending friend invites to friendly & skilled players so you have a bunch of online destiny friends at any given time. If you didn't post this from the official D2 companion cellphone app, go get it. It has a section called "fireteams" and is how almost everyone groups up. If you're not using the app you are probably playing solo. Most people also use PSN chat so make sure your privacy settings let you recieve invites to that of you're on PS4. Besides those things, forsaken is amazing. It's the best PvE that the franchise has ever had, and is where most of the playerbase is at right now. One last tip for a new player, google "destiny item manager" (DIM) and put a link on you cellphone. You can transfer items from your vault and postmaster anytime you want, and even create loadouts! You can create a whole set of armor and weapons for pvp, or stikes, or whatever and have all the items transfered to you with one click!

Do you make an effort to talk to others yourself?

I can see you are part of a clan. If they are not active or meet you expectations just switch clans :)
