Well then...
I was one of those who could hardly believe it when I heard the Medium Armor Skill was out in Oblivion.
After re-playing Oblivion a while back, however, and even Morrowind, I realized how daft these skills really are.
How much sense does it make to have a character with a Heavy Armor skill of 100, swap his armor
for a medium or light set, and utterly svck? Logically, he would wear such armor as if they were made of air!
It might work the other way around, but all in all, it's flawed from the start.
In my opinion, I think it would be best to either throw the armor skills out entirely, or narrow it down
to simply Armor.
Now, I know armor did slow you down in at least Oblivion... but they should emphasize this more.
Being armored like a tank should come with a hefty penalty to movement and/or Stamina.
If there is no Armor skill, it could instead be affected by Athletics. But since they say that skill is out, I hardly think that
will happen.
Now I realise people will probably say "Uhh! I want Light Armor skill for my rogue/thief/assassin/whatever!"
Well, even if it is narrowed down to one or no armor skill, wearing light or no armor would still be preferrable
for such characters for obvious reasons.
Heavy armor should slow one down, drain more stamina or what have you, and generally prevent you
from moving silently, softly, nimbly and stealthily. Plus, reflective metal is hardly ideal if you wish to sneak around.
Just look at Mount & Blade. It has no armor skill at all. Anyone can equip any armor (might be STR requirements).
You just have to be aware that heavier, better armor will slow you down considerably.
In conclusion:
I claim that one or even no armor skill is better than three, as long as the penalties for wearing armor make perfect sense!
Thoughts?
