Zoe Nerfs

The language on the patch notes is a bit confusing, and I was hoping someone could clarify for me. It says that "E travels less far, slows less, but lasts longer" on the top. As you read through the detailed explanation it says that they are taking the "overall" range out of that ability, but they are talking about walls when they say it. When you go down to the details, it says the range of E is lowered from 800 to 650 if it goes through a wall.

I'm confused. Is the range on the ability being nerfed when it doesn't go through a wall, or not.

I'm also not sure what they mean by "but lasts longer" The drowsy duration is up according to the patch notes from 2 seconds to 2.2 seconds, but that seems like a nerf if my understanding of Drowsy is correct, since you don't get the bonus damage until they actually fall asleep, which will cause you to have to wait even longer before you can actually land a Q on them for the bonus damage. Is the sleep time the "drowsy time" or is that the time you are slowed, and if Drowsy isn't the sleep, is the sleep time being increased as well?
