Heal/Shield supports

Can you please just nerf them so hard into the ground that they'll never be played again? I'm really sick of seeing Janna, Lulu, Nami and now even Sona running wild, not interacting with enemies in any way and just making their most favorite teammate almost unkillable. I never see Braum, Alistar, Leona and even Thresh has become rare compared to these champs. With those good old frontline supports I actually feel like I'm allowed to participate and interact with them. With Janna It's like "Oh, I picked a melee champ, well have fun guys, I'm not gonna do anything this game.". Really, it has become unbearable. Even in ARAM I often get into games where one side has an adc + heal/shield support and the game often is decided before it's even started. Please, allow melee champs to participate against supports and allow melee supports in general to be fun and playable...

PS: Absolutely not objective, in the moment I suffer from a similar disease to S4/S5 Leesinphobia where I can't objectively evaluate champs due to the frequency I have to bear with them.
