You can play this anywhere. I like this build either top lane, or bot kill lane. Leona + Darius bot (if match up permits) is just gg. Leona does extremely well against people lacking mobility/disengage that have either short range or are melee. Her immense amount of CC combines quite nicely with her AP scaling or AD if you can stick on people that well. Enemy team playing Zed? Not a problem. This is 50% troll 50% legit if you know how to play Leo. At least at low ELO 99% of laners wont know what to do when all the sudden Leona bursts them in her CC. I wouldn't trade much before triforce or AT LEAST phage though. Just have fun with it.
