But ogres and horses hardly serve the same purpose, do they? My point was that horses were pretty much useless as transport mediums, which is what I believe they were intended to be. Ogres provide variety in enemies, horses were just poorly implemented.
As for armor, what about just having an "armor" skill? The direct opposite here would be athletics (which should also cover acrobatics instead of having it as a different skill) . I know it sounds simple and dumbed down but hear me out: If the PC has high athletics skill, armor skill and armor itself would be arguably useless since the player can dodge attacks instead of absorbing them as opposed to being very skilled in armor thus allowing the PC to do the exact opposite i.e. absorbing hits instead of dodging via use of heavy armor. But the extremes are simple to deal with, the real problem is the intermediary bits, like wearing armor that isn't very heavy but still has a noticeable effect on character mobility .
In this case, both skills would be called into the equation together with the weight of the armor worn and the protection it delivers. Ergo, a medium armor oriented character aims at developing both athletics and armor skills equally, allowing the use of a "best of both worlds" type of armor balanced by the fact that he has to train 2 skill to use it properly as opposed to just one for either heavy or light configurations which aren't as versatile. Use of medium armor with a lacking athletics skill would have the same result as using heavy armor that delivers poor protection, while attempting to use it with an undeveloped armor skill would result in it behaving like a very cumbersome light armor.
Now, how does one classify the armor now in game, since there's no skills anymore? Well, the defining element of armors would be the weight/protection ratio. The armor skill is essentially there to counteract the weight of the armor enough to make it practical but only to certain degree so waring progressively heavier armor denies the player the proportionate amount of mobility. This way, players wanting extreme mobility as required for parkour like movement won't use armor and thus need no skill in armor since they are supposed to dodge virtually all attacks (which is rather logical, if a bit extreme) while player expecting various amounts of damage (wearing appropriate amounts of armor) will need the armor skill accordingly.
I'm not entirely sure if training both skills is enough of a disadvantage to using medium armor considering these characters will be able to use all armors at maximum efficiency since they will reach 100 in athletics and armor eventually. I guess if using medium armor trained the skills slow enough, this wouldn't be such a problem but it looks very hard to predict without any testing.
Furthermore, maybe using a separate "dodge" skill instead of athletics is better since athletics is already advanced by simply running and, if combined with acrobatics as I'm suggesting, by jumping too.
Also, third person was dull and useless in both TESIII and IV. If they added a subtle crosshair, it'd be more useful, tho there's probably more to making it equal to first person than that.
