It's nit picky to be sure, but I think about it every single time I'm force to make that middle click. To me the middle mouse exists for one reason, to scroll. That's why its a wheel! It makes perfect sense for a zoom for that reason, but not as the hold-click to rotate a camera button.
Many games use the middle mouse to rotate now, but I honestly can't understand the choice.
For me, in any game where I am given control of an orbital cam, reorienting the view is the single most common action I make while interacting with the game.
The camera is in near constant rotation, so the amount of discomfort there compounds quickly. WASD QE reminds me of fixed POV games from the mid 90s. I can suffer through it sure, but better and more elegant methods have existed for like 2 decades now. Like how often do I want to reorient my party's "formation" compared to how often I want to just rotate the camera? Cam control takes priority no contest, and right click doesn't even do anything else in PK. With zero competition, I'd choose hold right-click and drag mouse to rotate the camera any day of the week.
I know the whole concept of cam rotation is kinda new to the ISO genre, but damned if they didn't pick the single most annoying rotation bind for me. Hopefully they will open up their keybind options so I can can make it manageable. Right now I hit the wall on it in like an hour, same as I did in BG3 before they fixed it. Though here the solution still feels janky as well. Too bad
