Cool if it works for you!We do it a little different. We let HP work as intended, and the to-hit chance reflects that. However, at +10 is when you get a critical and that is the actual dangerous hit. That takes off of bloodied hit points, which you have much much less of.
And it is still fantastic!
As a DM most of the time, I find the nearly every attack subtracting HP annoying, and having the PCs have to calculate damage all the time tedious.
