Leona over Kayle
I'm wondering why Leona is the choice support over Kayle.
Leona has a stun, a personal shield, an engage and her ult. slows. Kayle has a heal, a slow, her melee turns to ranged that scales with AP and her ult. is a pretty big shield. Both have a passive that allows for extra damage and both have stats that are almost the same.
I haven't tried Leona, but i've played a fair bit of Kayle support and it usually goes ok. I also find that when people ask me to choose a tanky support, they disagree that Kayle is tanky. Leona has a tanky reputation but their stats are the same, and they don't seem to be that far behind Alistar's (at level 10 Kayle (1504 hp) is only 170 hp behind Alistar (1673 hp) not accounting for runes etc. Leona is 1446 hp) Kayle and Leona both have more armour than Alistar, Leona with slightly more than Kayle.
Thoughts?
