Oh, I know it is about game balance. And even if you can't move as effectively, you still have better reflexes and balance, etc. and I think it should help.That’s about game balance rather than realism. If it needs an explanation, you can say that heavy armor doesn’t add Dex not because it’s difficult to move in, but because it’s protective enough that being agile doesn’t meaningfully improve your chances of avoiding harm in it. I mean, look at the way the dude in the video just stands there and tanks that big golf swing from the sword. I think it might have actually been more tiring to bother trying to dodge that than to just take it.
So, limiting heavy armor to some DEX bonus isn't unreasonable. We house-ruled it to Light Armor = Full, Medium Armor = Half (round up), and Heavy Armor = Half (round down). So, you need a DEX 14 to get a +1 and DEX 18 to get +2 while wearing heavy armor.
Anyway, I don't want to get into a big thing about it. It is a good video and I hope people get a lot out of it.
