As an isolated incident? Sorta, yes. Rings typically have the strongest defensive enchantments in TES, so having one means less defense by far.
But more importantly, it doesn't bother you that they cut content without ANY logical reason for doing so? It's not like two rings is hard to implement as they've done it before, whereas you can say "why have me find a left guantlet AND a right guantlet, just give me a pair like they'd be sold in the store" you can't make that argument with rings and what's the result of only having one ring slot? Less character customization. Your enchantments and your armor are huge in defining your character and again, rings are like the best thing for enchanting. Since we have only one slot, then we can't customize our characters as much and they lose depth and personality.
And why? No [censored] reason whatsoever. No reason given. They just felt like it.
So yes, that does bother me when they needlessly cut easily implemented content that adds to character depth for no reason.
Does it bother me? Not when it's something as minor as one ring or 2. I was a bit shocked when I first found out that there was only one ring slot instead of 2, and yes, I wondered why, since it didn't make any sense, but after the initial "wtf???" I went on about my business and never thought twice about it.
When it's something minor like that, I may be disappointed that it could have been done better, but I'm not going to continue having a nagging dislike of it when it's really something that doesn't matter.
I don't feel that my character lost depth and personality because I lost a ring slot. I really don't. My character wasn't defined by that 2nd ring. My character's gear is only part of what defines him, not the entire package.
If you ask me what I would
prefer? Then I would
prefer going back to Morrowind's style of individual gauntlets, bracers, pauldrons, etc...
If you ask me if it
bothers me? No. It doesn't. It is so minor that it barely makes a blip on the radar.
