There’s a few things I like about third person.
No more back pedaling and wondering why the hell I can’t move backwards anymore. I can see it what I’m about to run into.
It’s much easier to see the full breadth of my weapon swing. Being better able to see my swing opens up a lot of possibilities. For example, looking to the side of my enemy, priming my swing, and then turning at the last second. This is something that I’m not as precise at with in first person as I find the depth perception better in third person. I don’t have to look straight at my enemy to have good awareness of where they are and seeing your weapon from a more top-down angle allows me to judge its distance easier than a straight-on view.
I find 1 vs many fights far easier to keep up with in third person. It lets me see enemies trying to flank me a lot better and allows me to position myself accordingly, whereas in first person I feel like I have to take my eye off someone much more frequently due to the more limited vision.
