Dear Riot, you may have forgot to nerf this champ last patch.
I know some champions are just very strong and have higher burst than others and you have to counterplay them to not have them 1v5 your team, but Diana, Diana is just too much. Diana has almost ruined this game for me. One game in particular, I was laning against a Diana, and once she reached 6, the game was over. She blew me up repeatedly, if my jungler (Volibear) ganked, it didn't matter, she just double killed us. Diana is ruining the game I am asking you to do your job as game creators and administrators to make her more balanced so that having her on the enemy team doesn't mean sure defeat. It makes the game NO fun playing against her, taking away the whole point of the game. Now to make this easier I've taken a look at her scalings, ability details, and general stats and I've devised a few approaches you can take to making her more balanced, you can take the usual route and decrease her scaling on one or two abilities, but I would recommend taking some damage off of her Moonsilver Blade and Crescent Strike in particular. Or you could take away the damage and reset aspect of her shield. I understand you gave her that reset so she would have more survivability, but trust me, she doesn't need it. Between her HIGH burst and having ANY shield, she might be too strong even if/when you make her more balanced. She NEEDS a nerf, and it's your duty as moderators to keep the game fun.
