Why did we even get a new scoreboard??

It's not even a significant difference, dude. Just a re-positioning.

In fact, it's easier to take note of which enemies are missing due to the positioning of the symbol.

You do know that Riot has many different groups working on the game, right? The people who are doing GUI changes have nothing to do with the Balance Team, who are the life long favorite targets of this board, or with the Champion Creation Team, nor the Skin Team, and not even closely related to the Lore Team.

The bunch of people at the GUI/Quality of Life/Clarity Team saw something that could be improved uppon and improved it. That's quite literallly the definition of their jobs.

Nobody complained, yes, but nobody complaining doesn't mean that it can't be better. Also, it's not like doing that took time away from the people working on balance, reworks, or anything like that.

personally, i wish they put back the number of wards your team has instead of the vision score indicator.
