Akali is above a 50% win rate by the way

51% for mid and 50.97% for top, those item changes really helped her out.

Top has a 1.28% pickrate and Mid has a 1% pickrate so the only people playing her are the Akali mains that are good with her. That's why her winrate has broken 50%
My gut reaction is "Reset assassin above 50% win rate? GUT THEM!!!"
But then I remember how tired I am with laning against 
and think "Akali sounds like a nice change of pace about now."
Maybe one of these days she'll break a 2% pick rate too
Item changes might have helped, still doesn't change the fact that she's still bugged and clunky, and Riot purposely won't fix her.
also you build tank and still one shot everybody.
