Amount of hp shown on health bar

[Apocolypze]

Don't you think our hp bar should show the amount of hp we have and how much we have left? Always in pvp after a fight people ask how much hp left and u have to make an estimate like 1/4 maybe 3/8, but wouldnt you rather know exact like, 172hp left, or u had me at 1hp! This can also be useful in PvE, where u can say, when i get below 300hp heal me ok? That's why i think we should have this in the game. Just my thought.
