Riven's chase is insane

Whenever I find myself playing against a riven it is a 50/50 split either they are not good with her and struggle extremely hard or it is a level 7 Riven main throwing out "gg ez" every kill. The worst is when you go to kill her and she can get out of whatever situation every 2 seconds as her jump has maybe a 6 second cool down. This also translates to her chase which is "fun". I get high mobility but there is not even a point to flash away as she will either jump the wall or still catch up. She gets a shield and chases so she kills supports regardless of what happens. It is not balanced at all, especially against supports. Having no way to outplay even if you are someone as op as Janna can't even get away with several knock ups. It makes losing team fights an instant "gg". Maybe introduce a new item that helps supports get way (I know you really hate ardent censer right now rito)

It is not just tilt this is a consistent issue and supports in general need more options to get away as post team fight if you are still alive and certain key members are not you have no way to escape against some quicker opponents.[sg-janna]
