And if you want to move a lot more i would say take waterwalking its very good

With the new meta of having a lot of ppl like irelia and graves on top is a bit difficult to play her right now
I dont remember the last time i fought a tank but my tip would be to take tp and try talk your teammates to dont push and get them to ward so you can tp and get free kills
If you are playing in a duo with a jungler or midlaner you can do some nasty stuff if they come top or you can help them on mid
