Stats are incredibly boring. People want to see upgrades that actually do something, stuff like perks. Those are far more interesting and tangible than leveling your CHR stat from 32 to 33.
Pfft, just give us stats that improve by doing the thing (eg. agility that improves by jumping around and visibly improves jump height every time it increases). I'd rather that nuance over a block of text with a witty name that gives a massive instant boon. Tangibility is right, but the numbers aren't the boring part.
Tell me about it. Skyrim for all its accolades kind of fails as an RPG in the sense that your character can do pretty much everything, but your run speed/jump height is static.
Increasing health/magic/stamina was a really lame way to handle levelling IMO.
It would be a shame if they streamlined the RPG systems even more for TESVI
"constantly be jumping while conjuring a skeleton" is pretty stupid and counter intuitive for an optimum thing to do, but it that's what you should do if you want to level those skills up.
Morrowind also had some bizarre optimum behavior if you wanted to get the +5s on stats when you leveled.
