TES series is one of the few survivors, perhaps even only single survivor, of the DnD fantasy age of the 80s/90s. It's being changed all the time, and I like change, but as that survivor, I feel guns would start to ruin the experience, all nonsensical real life comparisons and overly-discussed lore reasons aside. Bluntly put, I don't want guns in the series because I don't believe they belong.
I hear you there. Every TES game may feel different but overall I love how deeply rooted the series is in the heyday of DnD and the western RPG. If this discussion were perhaps taking place ten years ago, I might have had a different opinion. But I feel as if nowadays with every other JRPG and Warcraft wannabe adding in guns and airships, it's getting a tad excessive. I like the romanticized medieval feel of Tamriel, even in Morrowind I still felt its presence. I'd never want to see it go.
again if magic is so uber useful why are bows still around?
Bows are silent. They're lightweight and you certainly can nock arrows faster than you could ever load a gun. That is, assuming you don't want Bethesda to add in "magic" silencers and rapid reloading.
