So logically, a way of fixing the "Medium Armor Problem" would be to either increase the range of AC's (upping both Medium and Heavy Armor AC benefits) or inventing some greater penalty to wearing Heavy Armor.
I'd suggest increasing the armor benefit of Medium & Heavy Armors if it was me.
Let's see..... by +2 across the board would be a good place to start.
A combination of the armors as follows might work for you as well. You could have some slight weight/cost/max dex/arcane spell failure/check penalty differences between armors of the same AC. This basically puts 3 AC values in each of Light, Medium, and Heavy.
Padded +1
Leather +2
Studded Leather/Hide +3
Chain shirt/Scale mail +4
Breastplate +5
Chainmail +6
Splint mail/Banded mail +7
Half-plate +8
Full plate +9
As for movement, I use:
Light: 30/20
Medium: 25/17.5
Heavy: 20/15
in my game. 17.5 corresponds to 15 unless double moving where you would get 7 spaces instead of 6. This increases the utility of the "worthless medium armors".
