Petition to change Leona's passive

This whole Leona vs Diana thing got me thinking. Are any of you Leona mains(like me) out there sick of her being pigeonholed into being a very low damage support? Are you tired of never having any money, levels or build diversity on our favorite sun loving beauty?

I am petitioning to change Leona's passive. I feel it is the one thing really holding back her potential to be a badass sword wielding, shield bearing monster. It is the only passive I can think of off the top of my head that is 100% reliant on having an ally around.

Here is my idea, but you are welcome to post your own:

Passive: Sunlight When Leona's abilities hit an enemy target it applies a stack of sunlight, a maximum of three stacks may be on an enemy at any time. Leona's basic attacks and allied basic attacks detonate one stack of sunlight, dealing 35%-100%(Based on level) of her base AD to the enemy champion.

This small change, of making it able to be procced by herself and detonating based on AD, plus the ability to stack it on people. Would make Leona a lot more viable outside of supporting. But would also help her having better dueling power even as a support. Where if she has not built pure AP, she will be totally useless without her team. Many other supports are strong alone. Nami, Sona and Lulu do plenty of kiting and damage without their ADC/team. So I feel Leona should be able to do more than run or suicide without her team around.

Any ideas for her passive or kit in general? Post them below!
