I Think Leona Needs a New/Tweaked Passive
T4R, the main reason why I think this is that she receives no personal gain from her passive. She lights up a target for extra damage but has to rely on a teammate to do the damage.
I feel that this should be either scrapped or tweaked in order for her to receive some benefit. For instance, make it to where two consecutive abilities (from Leona) proc the passive. Then her OR her adc can follow up with a basic attack to deal the extra magic damage.
'es passive, dealing less damage but allowing allies to proc it for her. That would be disgusting. The damage would have to be nerfed by a lot.
