Just a free tip. Most of killing in lane is possible only if I can setup E stun with Q ready to follow. Problem is that if you just Q-E right away, you'll either push them away due to nature of E, or don't have enough damage if you Q in air to setup stun. You have to rotate around ready sphere and do whole combo at once.
It still works because people take those spheres just as visual scenery with no importance to them.
