Boeroer, ironically your idea about armor should have an negative impact on Stride and Deflection is almost like what DnD does.
Heavier armors reduce your movement speed and also caps how much Dexterity can improve your Armor Class.
So its not like the idea is a foreign one, if the grand daddy of RPGs does it ....
Of course I'd like it if we could actually SEE what our Stride was to begin with.
Actually AC in D&D increases the equivalent of deflection, it doesn't reduce it per se. There is no DR from (normal) armor. This I find a bit meh because it's obviously easier to hit somebody who's wearing armor. It's just not so easy to hurt them.
But a crit-to-hit conversion or a hit-to-graze conversion is ok. Your ability to connect with the enemy will not suffer (actually it will be even easier if deflection gets reduced) - but the quality of your hits will suffer if you glance off of armor.
That's partially true, if you are very good at builds in D&D 3.5, you will know the best AC builds are without armors, because armors has limitation on how much DEX bonus you can get, the heavier the armor is, the less DEX AC bonus you get. So a Monk/Wizard can get much higher AC with spells and WIS ac bonus than heavy armor fighters.
My understanding to D&D AC system is armor will cover the softest and weakest spot on your body, thus someone with plate armor is hard to hit because hits are deflected if they graze on the armor. I know this explanation is flawed because it cannot explain why the hell light armor like leather armor has AC bonus, but you get what I mean :)
