I think it says a lot that you hopped on D1 just to play crucible. I hope they make some changes to PVP first and foremost, including allowing us to play the game mode we want.
I like them both but they're very different. Like not "this is the sequel" different; almost feels like "different franchise" different. I hop on D1 Crucible to use my double-nade+double-smoke Graviton Nightstalker because there's nothing in D2 that approaches the level of movement/ability spam I can pull off there. But you have to take the bad with the good - you'll die to a Super or sticky nade or 1 shot Snipe/Shotty 10 billion times per match.
When I'm on D1, I miss the primary gunfights where I come out ahead and feel I outskilled an opponent. When I'm on D2, I miss the big plays where I can get 3 people down with a wombo + sidearm.
Fun detail though: I got real used to my assists counting in D2 lol. I feel absolutely robbed when I play D1 and somebody swoops in and janitors my kill
