There's two health bars for mobs. One in top and second in top of damaged mob
It's to complex...

Describe the solution you'd like
One healthbar is fine
And one in top of screen looks cool and informative

Describe alternatives you've considered
Second bar
In top of mob...

How to make this optional?

Additional context
In other case
Sometimes player just need big AoE to hit mobs through walls
And never needed to look in their health or rarity with level

it is optional. you can disable health bars using neat.
