This new HUD is horrible on my eyes and their's nothing I can do about it.
I have a vision impairment and have issues with certain elements of the HUD. Previously I made adjustments to the UI by modifying the .ini files that built it for the game.

Note the position of the team frames. I put them all in a nice even square (I can better focus on all of them at once like this) and enlarged them for better visibility.
This is what the new HUD looks like:

First of all Riot decided to make the teamframes circular for some reason, which my eyes do not follow well and makes it harder for me to tell certain champions apart. Second of all look how horribly small they made them. I'd like to point out that this is with all of the interface scale setting set to max. The health and resource bars are so tiny that they might as well not even be there.
Now originally this wouldn't have been too much of an issue for me. On the PBE I actually modded this new HUD to basically make the teamframes like I had them before this update, and I had it ready for when the HUD was released to live, but as it turns out Riot decided at the last minute to get rid of the .ini files and shove everything related to the HUD into binary files that I cannot modify. Now I'm stuck with whatever options are available by default and they simply aren't enough.
