Maybe Nexus Siege would work better on the Howling Abyss, no?

I don't really like that game mode :P What's your data on it rito? Are people playing it? :C I don't feel like so because none of my friends invite me for that mode, we just go arams instead.

Maybe in it would work better in the ARAM map.

Plus that huge chunk of the Summoners Rift that is blacked out doesn't look any good. I think the mode needs some objectives for the offensive team in its own side of the jungle, but if the one guy is not sieging then he'd be losing an outpost or something. The game doesn't have to be one attacking team, it could simply be a non-mirrored map, with one team having better buffed offensive-scaling (like it currently is) but with different towers, focused on sieging (tankier minions, spawning faster and dealing a bit more damage?)
