How good Is Diana jg

I've been seeing alot of Diana jg lately. I needed an AP jg that isn't hard so I decided Diana jg. I just got done with my first game and I carried it. That's not even the best part. Our ADC got jealous of me I guess and started intentionally feeding. She claimed I was "ksing" while I was just kind of going for kills once I hit 6. We won that game. All I said was I was popping off and the first thing I see her say is kys. I also saw she said come mid for free kills and in an attempted to trick the bot, she just went places alone and said where she was and tried fighting alone to die. She even inted a dragon. Luckily she got banned seconds after leaving the post game. Anyways, the point was I won on my first attempt and we had someone inting on our team and I don't exactly know why and I was snowballing pretty damn good. She just kept saying I was trolling. Welp I got to remove a tumor from lol. I built full AP Diana that game. I was even against a galeo. I just kept deleting squishy targets. Her ears feel kind of slow but I was still able to full clear no problem. she has great burst. She even scales good. Her main weakness is tanks because flat damage. No % damage. That goes for basically any mage or assasin. Her ganks are bad pre 6 but after That, she's strong. I'm thinking about taking her in ranked. What I want to know is how good of a jg is she. So is she a good mid so I can only play her. the
