Any chance for Leona to...

...gain better scaling on her W defenses? I mean, shes fun and all and I enjoy playing her but her tankiness falls of WAY hard compared to other tank supports later in the game. She feels strong when played well but by 15 minutes her defenses crumble like paper unless super ahead. Can we get some love for the sun? Maybe instead of a flat 20% bonus armor and MR how about bonus 20/25/30/35/40% armor and MR?
