I think trying to relate skins with the map is a joke and Riot won't take you seriously if you go down that road. That's like a 5 year old crying that they will not go to school because their mom didn't buy them that shiny lollipop at the store.
I think the new map is ugly, but I have always said this ever since it's early preview. Riot will never change it now that they have put too much work in it, however. I seriously doubt they will fix all the issues that we have been talking about for months and months now. The map is too grey, pastel-coloured. Riot has backed this up with an excuse of "layers", with the map being the bottom layer and thus must be more desaturated than the champions ("middle layer"). From an Artist's point of view this is a load of bollocks since the champion visuals are supposed to be immersive and work with the environment, not against it.
Put any of one of the hundred champions on the new SR map and tell me that they look like they belong. The truth is they just don't. Nothing belongs in the new SR map, even if Riot is trying it's hardest to create a theme for itself (like those ugly mutant birds and frogs on LSD that keep popping up in LoL lore). Even the store's base doesn't look right -- "Hey guys, the enemy team is pushing our nexus, we should all corner ourselves into that very narrow over-hanging cliff that is falling apart, we'll be safe there. Surely they can't get us."
As much as I used to have faith in Riot over their service to their fans, I think they have also partially given up on us. Much of the league community is quick to complain about the smallest of things and so I feel like Riot has learned to ignore a portion of the feedback and label it as irrelevant. The only times Riot has really changed something about league is when a massive voice is put forward and the community groups together to be the loudest opinion. But relying on the loudest opinion alone will not do for the new SR map. It's the smaller crap too that matters here.
The map itself looks like a horrible resolution. I thought that even if it was ugly and washed out, the scale is all wrong. The floor in the base is made of massive flat stone with no textures at all, and the map is very pixelated. It looks like a smaller resolution stretched out to fit my screen. Nothing about the textures fits at all. The models look GREAT, the towers are GREAT, everything that is 3D rendered looks massively polished and extremely beyond my expectation. But the 2D textures still remain blurry and pixelated around the edges like as if they are not in HD, which is a big disappointment. Especially for myself, as a player on ultra-high settings.
