Diana hasent hit 50% or over win rate in ages
Are we going to talk about how champion.gg doesn't even have a jungler slot for her anymore? Or the fact that she simply hasen't been over 50% in a long time. In fact I don't think I have even seen her hit a solid 50 than hm, season 6? I may be exaggerating and maybe one patch she was super strong but that seems to escape me. They did some b.s compensation e buff but that's all ive seen for her
also hurt her, since she lost some of her damage and because
is a go to MR item, she can't get her Q onto the carries she's going for as easily. (ap mid laners)
tank item+Boots of your choice. The thing with this build is that you'll be able to deal a crap ton of damage with ROA and Nashor's as your first two items, you'll also be able to 1v1 tanks and other diver's/fighter's effectively, when you get zhonya's you can engage for your team with Q+R+E+Zhonya's and by then you'll have 3000 health anyway because diana has some ridiculous base health at level 16(usually when i end up with zhonya's) death cap to keep up with ADC's damage and a tank item to make yourself even harder to kill, it works tremendously well. 53% Winrate and i should note i am mastery 6 with her almost mastery 7 so even though my Op.GG doesn't show more than 15 games with her i know for a fact i'v played PLENTY more with that and i always find success with her.

thanks to rappel. Can't really think of what match up you'd pick diana for.
