Title says it all. Whenever there's splash art update, we get to look at more hideous mini map faces. Think about Vayne first being changed, Ezreal first changed having a completely blue mini map face... Katarina definitely looks worse, ect. Riot, how hard is it to really examine the effects you're having on a map we have to stare at all game? Should be common sense.
It's cause the new splashes have a lot of detail which doesn't scale down well, versus the old splashes which had very little detail so the splash itself looked bad but the in-game icons looked great when scaled down.
The reality is that if you want really high detail splashes with the dynamic action poses and atmospheric lighting, then the portraits/mini map icons need to be completely edited to look good, you can't just copy/paste from the splash and shrink it down. Lately they HAVE been editing the icons, but you can tell it's being done very lazily/sloppily.
