No seriously we need to talk about Leonas 2 year old bugs
Leona has 4 extremely long standing bugs that are not being patched, and they have been there since her release almost.
1. Shield of Daybreak goes on CD when effect isn't used and target dies.
Remember when Nasus and Garen got that nice fix where if they turn on Siphon Strike/Decisive Strike and go to kill a minion but the minion dies first and the ability goes on CD without giving CS? This is that bug but with Shield of Daybreak
2. If Leona uses Shield of Daybreak to reset her auto attack timer while attacking the enemy nexus, she will automatically throw her Zenith Blade in the opposite direction.
Not much more to say, start auto attacking the enemy nexus and mid attack use Shield of Daybreak to reset your auto attack timer and it will put your Zenith Blade on CD by automatically casting it in the opposite direction of your auto attack.
3. Occasionally when Leona uses Shield of Daybreak to attack the enemy nexus while she is already attacking, if you use it when you auto attack is up instead of using it to reset the timer on your auto attack, Leona will do circles around the nexus as if it is out of range of her attack.
**4. Zenith Blades' warp is inconsistent on which abilities stop it and which don't. IE, Vi's Assault and Battery can't stop it until Leona lands, but Threshes' Flay can. Malphites Unstoppable Force can't stop it but Jannas' Howling Gale can. **
Seriously make up your mind, this is extremely inconsistent and causes a lot of problems while trying to learn her/play her.
