Mordekaiser Bug- Dragon Leash

So, I'm putting this here since it wasn't mentioned as intentional in the patch notes or anything, so I'd consider it a bug (or stealth nerf if it is intentional).

Currently, Morde's dragon ghost has a leash range, something the dragon ghost never had before. You can check it for yourself in a custom match, but if you subjugate dragon, it will port around after you rather than stay put on the map where you wish him to be as you used to. If it was an intentional change or nerf, then it just wasn't listed.
