Firstly, I want to clarify that this is just a suggestion, NOT an offense.
I found that that Spiral Knights has some flaw in managing and displaying health bars, like:
1) The health bars of monsters. We should at least see how much remaining life the enemy has after it gets hit. This can greatly help the knights to plan attacks on monsters and not guessing how much blows to be delivered before knocking down the monsters (especially in the arena)
2)The knights themselves. We know that as knights go deeper in the Clockworks, their max. health will increase gradually. What if the max. health gets so great that the health bars have to squeeze into tiny ones? Or the health display only shows limited number of health bars and not the actual amount of health? So, it is much better to display the knights' health in numbers rather than bars. Besides, we can estimate how much damage the monsters deal on ourselves through this way.
Hope the developers can get this!
But some people will complain about how easy it will make it if you put it on the monsters.
And with the Knight's HP, it can only go so high, you have 5* gear which gives you a what, 5+ HP increase each, then the 15+ (is that the highest, I forget)vitapod, so they already have it covered. It can't go any higher than that.
