Why Leona&Blitzcranck need a REWORK

Hello fellow summoners :)

Why do i think that Leona&Blitzcranck need a rework? First of this isnt a Leona&Blitzcracnk are OP thread,i know how to play against these champions,but i dont like playing with them. They are both agressive support who can get teir ADC fed if the opponent makes a mistake in their positioning,but if their ADC get attacked their isnt much they can do. They can use their R and dive into the fight and die while defending their ADC/or die instead of them. What im trying to say is they need more defensive mechanics,while they would still be able to play agressive(look at Braum&Thresh ->2 agressive supports that also can save their ADC wihtut giving a kill to the enemy team). Utility support(most of them)dont need to risk their life to save their ADC,they have nice disengaging mehcanics thta also allow them to play agressive if needed.

Second,i know most of you like Blitz&Leona the way they currently are,but they could be so much better and healthier for the game.

So pls & just want to better protect their ADCs,so pls lets make their wishes come true ! :Đ

PS. I will try to come up with ideas for their rework(hope that happens today)
