Diana
As someone who loves Diana, it bothers me how little attention she receives!
Diana has a very very bad early game, I feel like if you don't get constant ganks, early kills, or lucky with your opposite laner, you are next to useless as Diana. You might get a power "spike" at 6 but if you die atleast once that is gone and you will be feeding off the entire game.
Another problem that I see with her is every item in her build is 3k+ gold! which isn't a problem many things are expensive in other's builds, but Diana's items usually only have from 2 to 3 items to build for the last item, meaning most items cost up to 1k gold to just build part of it! making it feel super slow and useless in the long run when you do no damage and can only farm when you are doing well and are ontop of the other laner... anyone else feel like this?
and
which is a 14,000 gold build. It takes too long to get strong and are easily countered by adc items like
and
which are standard items.
