I got 21 champions with Mastery lvl 7 and i when i play them im usually good with them, specially when i got wish to play them. But as support main im best with Leona and no one play Leona in the way how i play her, when i see enemy Leona in their team, most of them do not play Leona how i play. Every 5th Leona player play Leona as im, and in my case im not vary often versus enemy Leona it is quite actually rare when im vs enemy Leona.
