I feel this at a personal level. I have friends from D1 (raid and trials teams) as well as irl friends that have gotten D2 that hit me up for story missions, or just casual playing that I'm just not a fan of partied up. I hit my destination with a mission, and when I fulfill said mission, I'm on to the next agenda. It's not fun for other people to join in on me while I'm handling my business, but that is the way that I enjoy the game and feel like it's most rewarding. Now don't get me wrong, I absolutely love helping out. Whether it's a friend, or if I see a level 5 on a public event, I will turn it into heroic and carry them through for rewards, or experience and stuff like that. I'll weaken enemies for them if I see they're going for an objective, and I always wave/emote when I find a chest and/or materials. I've helped friends get their exotic weapons, but I refused help when I was at 240 light going for the mida on the quest that required 260. I don't mind partying up with a friend if we have the same objectives, but I'm not gonna run around and do patrols afterwards if it's not on my agenda. I haven't joined a clan because I'm waiting for the right group of bamfs that know the ways of the NLB from D1. That was the only thing that kept me playing in D1 honestly. Wrecking whole fire teams with nothing but the no land. Ahh the glory days
