Now I've relaxed the grind of power, I'm really enjoying focusing on Triumphs. One of the most underrated additions to the game. Everyone loves a checklist of stuff to do and ticking it off. The seals are a nice little additional touch to aim for as well.
The variety of public events to make the go heroic are also fun to move around to go and do.
Gambit is ace, but arguably only in a group that wanna play it. The strategy of mixing peoples Supers up and sending people across to change how the round is going is really challenging but fun to play.
Although I've not done many, I enjoy the raids in D2. Especially the previously dubbed Raid 'Lairs'. We always have had issues getting people together due to length but they are a nice time and also not too heavy on mechanics that people can learn.
Pinnacle Weapons are a great addition. People should focus on these more so as they have unique perks and enough to give you at least a few guns you can use in certain situations.
Exotics. Yeah, dont hate me but being honest, the exotics in this game aren't as bad you think. Theres plenty to get and they've brought back enough D1 exotics to keep some nostalgia. I dont get the issue with old ones returning if introduced in a decent way.
More missions like Whisper of the Worm and Zero Hour are desperately needed. Amazing content that take some time to get your head around and get done.
Dreaming City in the main is the best place they've ever created. Lots of variety of missions and modes to play. The dungeon is something that if we had 5 or 6 more of them I think people would stick around more often.
