I have something to say about the new UI.
I wish I could leave some feedback for the new UI, I really do. I want to tell the developers that the UI should be transparent so that if there is an enemy champion behind the minimap area, for example, players can actually see that champion approaching ahead of times or something like that. I get that it's not a big deal for most people, but they said something about less obstruction, right? If they want less obstruction, they could make the HUD transparent so that players can see what is happening on all parts of the screen and not just the certain parts. It will not make a huge deal, but it still should up the reaction speed a little bit, and the UI might look more advanced in the long run.
I don't think anyone will listen just because I'm not level 30 yet, though, but I am experienced in various games. Seriously, I think all people should have their say to the HUD development... but I still have a hunch saying everyone would go "GET LEVEL 30 OR SHUT THE @#$% UP YOU NOOB!"
