Legend
It's all nice and cool to have +3 sword and +3 armor but that kind of breaks the 5e premise of bounded accuracy and usefullness of low level mobs(especialy low level mobs with high AC as their sell point)
So instead of giving +1 attack and damage, weapons would just deal bonus damage.
1st version is all are equal and weapons gain +1d8 damage per point of "plus" they have so +3 dagger would deal 1d4+3d8 damage while greatsword would deal 2d6+3d8 damage.
2nd version is based on the weapon where a "plus" would deal that much of weapons base damage die, then a +3 dagger would be 4d4 damage and greatsword would deal 8d6 damage.
this way weapon does not "guide" it self to the target, that is 100% left to the skill of the wielder, but it is so sharp and deadly that when it connects it cleaves through about everything.
As for armor there is also two ways.
1st; damage reduction. 2 or 3 points of damage reduction per plus. this is fine and easy but it has a problem of going into "singularity" especialy if combined with heavy armor mastery.
If it's 2 pts per plus of armor and heavy armor mastery, that is DR 9. It could render many low CR mooks completely useless expect as a off chance pest with some grapple or push attempt.
2nd vesrion would be bonus HPs, like 1 or 2 or 3 HP per plus per HDs of target. So 20th level character with +3 armor could have +60 or +1200 or +180 HP.
This way bounded accuracy is maintained and it's only about damage/HP balance.
