I am a necromancer of threads! xD
I was actually looking for if there was a reason I keep getting put at Purple Nexus as a starting point instead of Blue, but then I saw this, so...
I play with a locked camera by default, and while I can use unlocked from playing Dota 2 a bit, playing with Orianna's ball with a locked camera is hard enough because it has a leash range that goes beyond the top and bottom of your screen already.
If you're playing unlocked it's just a living hell trying to keep track of where you are, where your ball ended up (especially if you used it to help protect an ally), try to figure out where to place it next, if it can get there in time to even do anything(screw your travel speed nerf Riot -.-), if it's better to try to tether it back to you (or will your ally be running toward you, making this impossible?), etcetera.
Given this is a pretty isolated example, she's an official implement in the game, and I don't think you should be screwed over ever more by having to try to work around a bunch of boxes that could easilly have an option to be allowed to move to the top of your screen to make life a little easier.
