I'd prefer a stronger single target heal then the 2 target heal Kayle currently has

I would too. I play support kayle and max heal first. That heal turns into a beast. I'm gonna miss it

I know that kayle players would prefer it. But yknow why it works that way? Because kayle can't have ridiculous laning sustain. She's a hypercarry and her laning being shit is 101 of her design. Making single-target heal stronger would make her laning really strong against enemies with weak/mediocre poke

The two person heal is to make her heal valuable in team fights without making it oppressive in solo lane/jungle. (Aka. The Nidalee problem.)

As a kayle supp main I am disappointed with the Nerf to her heal. Honest if you're playing her right she takes little to no damage. Prime example look at the gameplay video when she and Morg take on the enemy team at Baron. Having her heal heal both her and her ally in exchange for being weaker with a higher mana cost and the same cooldown is more often than not a Nerf.

Not gonna lie, it would be nice to have the option to heal yourself for 100 or heal an ally for 50 while you get 50 or something like that. Or maybe you can heal yourself for 50 or heal an ally for 100 to further lock in the idea that she'll sacrifice herself (ulting an ally causing her to not be able to do anything for a couple seconds) for the betterment of her allies.

The numbers are obviously simplified to better show what I mean

I prefer if she was like Taric, more heal if alone, less heal if shared
