Bonus stats are pointless

Because they are small enough to be functionally zero. Let's say you have 1,000 health and you are hit for 300 damage per attack. You have 5 bonus health.

1,005 - 300 = 705
705 - 300 = 405
405 - 300 = 105
105 - 300 = dead

Now let's try with zero bonus health.

1,000 - 300 = 70
700 - 300 = 400
400 - 300 = 100
100 - 300 = dead

Either way, it takes four attacks to kill you. Functionally zero. The chances of the bonus health saving you for an additional hit are infinitesimally small. A thousand players playing for a thousand hours, and I'd bet you could count the times it mattered on one hand.
