Suggested change to make Leona Top viable
I tried running Leona top in a few games now and what strikes me as a bid problem is that she lacks any sort of sustain. Twice casting all 3 of her spells will put her oom. Not a big problem when running support but with her low dmg really puts her out of sorts top. And even with her W, she will still get warn down faster then she can do dmg. VS a ranged champ, she's already lost the lane.
My suggestion to make Leona more then just a bot support is to add some solo functionality to her passive. Right now it's useless when she is solo. I suggest that if the sunlight is not triggered Leona reabsorbs it for some health and mana. That way she has some sustain solo, but keeps the bonus dmg when grouped. This change wouldn't have much of an impact on her current roll as support, but would make running her top side, and maybe even jungle, possible.
Thank you for considering my suggestion.
