Using 3.5 like wording since it seems this edition is back tracking.
Have all armor be of use in 3.5 only like 3 or 4 types of armor were ever picked by anyone.
Type 1> +1 AC +9 max dex -0 skill penalty example = robes, heavy clothing, ninja garb
Type 2> +2 AC +8 max dex -1 skill penalty example = soft leather, elven weave cloth, chain bikini
Type 3> +3 AC +7 max dex -2 skill penalty example = rigid leather, studded leather, chain shirt
Type 4> +4 AC +6 max dex -3 skill penalty example = light scale, chain mail
Type 5> +5 AC +5 max dex -4 skill penalty example = scale mail, heavy chain, banded mail
Type 6> +6 AC +4 max dex -5 skill penalty example = breast plate, samuria riding armor
Type 7> +7 AC +3 max dex -6 skill penalty example = light plate armor
Type 8> +8 AC +2 max dex -7 skill penalty example = plate mail
TYpe 9> +9 AC +1 max dex -8 skill penalty example = field plate, dwarven plate
See now every armor has something for someone depending on what dex they have you will see a large variety of armor in different games.
This also lets you be descriptive with what you are wearing becasue the name of the armor and what it looks like is just fluff, the Type is important so you can be wearing gladiator peicemail and it be any Type.
Do the same thing for weapons all weapons do a d4, d6, d8, d10, or d12. Have d8 be the base main hand weapon like a long sword, warhammer, flail ect. The d6 has either reach like a spear or off hand like a short sword, d4 has two key words like thrown and off hand.
All d10 weapons are two handed with one key word like reach, d12 is the standard two handed weapon.
2d6 is not the same as d12, 2d4 is not the same as d8 please stop using multiple dice as base damage.
Have key words that mean things like piercing, slashing, light, reach, fast, slow, ect...
If it has a negative key word like slow then it gets an extra positive key word.
This way all weapons follow a standard design formula that matter to the game not to simulating reality. This is a fantasy game reality matters so little it should never be used as a justification for bad game balance.
Remember this is a public forum where people express their opinions assume there is a “In my humble opinion” in front of every post especially mine.
Things you should check out because they are cool, like bow-ties and fezzes.
