Is KDA a good thing? can it be something better?

Currently we use KDA (kill/death/assist) as a way to gauge the current power of people in the game we're playing and to some extent player skill; but I wonder is that the best way?

what about CS, counterbuilding, lategame champions, or support champions; aren't these facets of skill and power that are oftentimes disregarded in favor of KDA?

And of course the wild inaccuracy of KDA as a measurement of skill/power given to the fact experience and gold come from a variety of sources i.e shutdown gold and diminishing value of high death targets; but when things look unfavorable it's always "omfg 0/7 noob stop feeding" when in actuality he's 0/7/19 with 300+ CS and playing his hardest to help the team has he made mistakes? of course but he's not letting that get him down and he's going for the win.

that's not to say KDA is useless for observant or experienced players it can still be useful as a situational measurement or for new players a goal to improve on "more kills than deaths? I'm getting better!" but is it really necessary for everyone to see it rather than something more accurate? maybe current gold earned and/or current bounty since items, summoner skills, and level are already shown.

I have a tendency to ramble so I'll try to outline my thought process here: most of the time I see KDA or more often K/D used as a vehicle for Toxic behavior but simply removing it would be detrimental to the games health without something to replace it's natural functions and there's no real reason to remove it from personal HUD or match history but several reasons to remove it from the crosshairs of disgruntled players.
