Rework Graves

For a while now I've felt that graves was pretty underwhelming. I've tried him around 8 times so far during free rotations and against other ADCs he seemed pretty weak in comparison. His range is okay since he's wielding a shotgun, kinda makes sense, but sadly his AA damage in hardly compensates for it. Also, his abilities just don't seem rewarding enough to compete with others, especially in comparison to mana costs. You see Graves's Q take out a hefty amount of his mana while a Lucian can poke with more damage and half the mana cost, seems pretty unfair. Furthermore, though I know he's more of a late game champion, I never really saw anything to be excited about over his late game in comparison to his mostly farm oriented early game (due to the range and lack of serious harassment compared to say, caitlyn or jinx) while you have champs like twitch with a similar early game who became the face of terror late game. If not an ability rework he should at least have a numbers rework so that he can compete with other adcs. feel free to share opinions.
