At first it looked pretty weird to me, however, after playing some time I realized, that it's not that bad and that it's actually very cool map. Of course, there are few things that should be changed, guys in previous posts mentioned sound problem of turrets and stuff. And one thing I'd like to add for turrets topic is that they should have a collapsing sound, when destroyed ( maybe there was, but I didn't hear anything ).
As for everything else, I'm very impressed with the new Summoners Rift map and I cannot wait, until it replaces the old one. Well done.
