On the reactive abilities:
How often do 14th level Barbarians ever get reduced to 0 HP. They're probably going to have something like 120hp or so. And an ability which triggers on 1 out of every 20 opponents seems kind of weak.
Might I suggest instead that you can trigger them on being reduced to below half-HP and that you loose the benefits if you raise above half-HP. I also don't think 'every hit is a critical' is a good balance here because it allows you to game the system by stacking too many damage dice. Perhaps instead just double the Rage damage bonus versus that target when you make a Reckless Attack and any damage you take from them when they have Advantage also gains your Rage damage bonus. That's a lot more mathematically predictable. The crits only version really benefits opponents with high damage dice but low damage adds over the opposite. Like an enemy that does 1d8+2 is way better off than one that does 1d4+4.
