The Division 2 was basically my jam for almost two months solid. It's the first service game that convinced me to play through its endgame, instead of dropping out as soon as I finished the campaign. The journey from level 1 to World Tier 5 is pretty fantastic--some difficulty spikes here and there, with the accompanying growing pains--but in the end I loved it all.
The problem, as many others have already mentioned, is that once you got to World Tier 5, your progression slows to a crawl. Most of the game can be soloed, which I very much appreciated. But the most significant piece of post-launch content is a raid that a) requires a great deal of coordination and grit (which is fine but by its nature locks out a lot of people), and more importantly b) didn't seem to deliver when it came to quality loot. I remember thinking that I was going to return to the game when the raid came out, and even signed back into the Era Discord to register my interest in joining a raid group. But it never happened, and I didn't really go out of my way to make it happen. I just got put off by how difficult it was for everyone when it launched, and it gave me Overwatch-style concerns about the potential for toxic groups and not feeling like I was pulling my weight because I didn't have the right build or wasn't fast enough at killing things or whatever. Plus there were all these other newer games I wanted to play.
The Division 2 was a great game and I enjoyed my time with it immensely. But I'm not sure what it would take to bring me back at this point. I just feel like I've moved on.
