I've been a leona main for the past 3 years, so I am somewhat bias hahaaha. I have roughly 250k pts on the champion because I don't get to play as often as I would like, just mainly during the weekends.
I do love the Project Leona skin, which is my go to. Feel in love with it as soon as it came out and has been my go to champ and skin combination for just about every game where I get to counter the opposing support. I also play a lot of alistar.
