Rek'Sai: The Worst Jungler you will Ever Love.

I love playing Rek'Sai, since I first played her it was great, played her on Free Champion Rotation, then bought her with Blue Essence, and here is where my issue began, she is super fun to play, the plays you can do, the combos you can get and those all-in dives with your ultimate, however, she has no prominent feature, if you look at her champion stats, it's all balanced, a perfect circle, neither tank nor damage, neither rage-inducing Crowd Control nor scary burst damage (Rengar) it's just plain yet not boring, I always play her, I always have fun with her, however, I never get a satisfactory score, I end 10/6/4 or 6/12/6 and things like that, so I just mean her to be buffed, either make her a bit tanky or give her some damage, ganks that with any other champion would be a sure kill (Bruiser champions) end up in my death, since I don't have the damage to end him up or the tankiness to fight long enough for the kill, also, I feel her passive somewhat low on early game, and her Q lacks some area damage, this is how I personally feel, if you have any tips on how I could improve my playstyle or maybe Im missing something here I will gladly accept it. Thanks for reading my thread!
