I'm looking to set up a dual boot system with Windows and Linux Mint, but I'm wondering if I should just reinstall the Windows ISO and then Linux Mint, or if there's an easier way to do this without a complete reset. I'm a Destiny 2 player and I've tried running it through Wine and other methods, but it's been really laggy. Any advice would be appreciated!

If you’ve got enough space, you could partition your drive for Windows and then just install. After that, boot with a rescue disk to reinstall Grub as your main bootloader. If this sounds a bit too complicated, going the reinstall route you mentioned might be the easiest option!
If you have two drives, a good approach is to unplug the drive with Linux when you install Windows. It’s generally a best practice to have one OS per drive, as dual booting with a single drive can be tricky. This way, if something goes wrong, you can still boot into the other OS without any issues.
Why not play on a console instead? But if you definitely want to dual boot, I recommend keeping each OS on separate drives. Windows tends to mess up shared drives, which can create problems down the line. If you can, you might also consider setting up a separate PC for gaming and keeping your other OSs for daily use.
A solid method is to use a Live USB, like GParted Live. You can shrink your Linux partition to make space for Windows and format it as NTFS for the installer. After installing Windows, it will overwrite the bootloader, so you'll need something like boot-repair-disk to get Linux back into the mix. Just make sure you have enough space for Windows—about 50GB minimum for Windows 11 should do it!
I completely get wanting to play Destiny 2 while still using Linux. Dual booting is definitely the way to go! Ideally, you should install Windows first and then Linux Mint. If you're new to this, make sure to backup your data and maybe check out some tutorials. Best of luck!

You can install Windows after Linux if you need to, just remember you'll have to fix the bootloader afterward with something like a boot-repair disk. While it's easier to do Windows first, don't stress too much if you're past that point!
