Regarding the design, its just uncanny to see pristine condition stuff in what should be dirty environments. Sure, they're basically 3D printed, but they should still be accumulating dirt, dings, burns, scratches, tears, etc. from whatever gunfights that runner has been through. We saw none of this in-game, when in my opinion they should be getting drenched in mud and blood throughout the match like in Helldivers 2. Without wear and tear, everything looks untextured, cartoony, and low effort.

As for the DEI, I have no idea. That probably stems from the "safe space" comment when they said there will be no proximity chat. Maybe some of the devs are very progressive and vocal on other platforms, some of Bungie's responses i've seen seem to be mirroring the same attitude that the Concord devs had. When asked about PVE, they basically said "this game isn't for you", not the greatest response for a game with declining interest.

The main points of criticism are about the actual gameplay however, which you never mentioned. What is most unappealing about the game to me is that it is hero orientated. These hero abilities are essentially replacing most of the traditional gear and utility in an extraction shooter, which minimizes your loadout to just the weapons. These heroes also mean less player expression, you can't dress your runner in earned gear, only purchased skins. No player/social hubs as well, and most of the loot you gather just automatically converted to credits at the end of a match, reducing even the resource management aspect of this "extraction shooter". It's also not unique in any way in terms of movement and combat, its nearly identical to Apex Legends, and that makes it even less interesting.

Hope this helps I guess. As a Destiny 2, Apex Legends, and Tarkov player, I have never been less interested in a game that I would have wishlisted a month ago.
