Okay, @Darkside Eric. Let's recap to make our points. (I've thoroughly enjoyed your topic, btw. Really good discussion).
What exactly are the differences you want from Skyrim as it is now, at end game?
If you want races to be so distinctive from one another that it makes a strategic difference to game play at end game I am passionately against this. If one race clearly makes a better warrior at end game than another (like more skill or stats), then I don't believe this is in keeping with the spirit of free choice I'm used to in TES games.
Why are you wanting changes to races, and not to something like just skill sets in general, say?
Then we are going to disagree time and again on this, because you view it as a "half empty," a one race being naturally better means other races can't choose to follow what they want to be, where as I see it as "half full," because I wish the game to be optimized between race and archetype of a player decides to pursue the archetype attached to the race of their selection. You see "well it's not fair that a High Elf can't be as good as an Orc as a Warrior," whereas I see that's how it's supposed to be because that's why races were given archetype bonuses in the first place.
I offer the change to races (I've done changes to skills as well) because I feel it's the easier way to go rather than evaluating every skill and creating one, or a handful, of different bonus that could be applied to all races.
Congrats, you figured out that the game in particular doesn't respond very differently to different race choices. You so smart. Anyhow, role-playing isn't all done by the game, sometimes a person fills in the blanks. Have you taken the time to see any role-playing Lets Plays? You could learn a thing or two.
In addition, if you're going to argue that 50% Fire Resist is significant in the end game then I don't think you have the appropriate knowledge to even be participating in this conversation.
Bolded part: Correct, but when the game breaks its own narrative, it's kind of a problem. I roll a Khajiit the same way I roll a Drow in Dungeons & Dragons, I know and
expect to get flak for my racial choice because that's how the narrative of the game world works. When the game world goes against the way it says it's supposed to work that hurts immersion.
Having any kind of Resistance is relevant end game when you are facing off against opposition that uses what you are resistant to and can, at times and often, mean life or death for your character. That's why people build full Magic Resist armors.
