Health bars?

This isn't really a suggestion, it's just that how come monsters can't have health bars, i mean this game's been out a while, and no health bars? At least put them on bosses!
Can someone explain to me the reason why we don't have them now? At least explain the cons of this feature.
Thank's for reading and/or answering :)

Generally, the monsters die so quickly, you won't need to care about how much health they have.
Other reasons:
-Distracting animation on your HUD.
-Unnecessary clutter of your HUD, considering quite a bit of SK involves getting mobbed, and displaying all of those bars could be annoying to see past.
-Lag from the extra animations.
-Stuff I can't remember.
no health bars in dat game nonetheless theres a patch for it
why?
makes the game too easy.

The devs are insistent on not giving numbers for health. Giving enemies health bars would make it so people could easily figure out how much health enemies have.

It would make SK even more of a math game than it already is.
you can see how much shots you need to kill and make a graphic

Or Halo.
Or Mario.

Skyrim has health bars. And look where that landed them.
Ahem, use the search bar next time, kay?
