Why is Kled more of a dual champion than Kindred is?

This isn't a rage post or anything of that sort. I'm just really curious as to why Kled's kit has more duality (not sure if that's the right word to use but you know what I mean) in it than Kindred's when they're both two man teams. Lore wise, Lamb and Wolf are both very much expressed in their kit but gameplay wise, not really. Wolf never really feels important to me when I play Kindred, he just seems to be there. Nothing more than a visual representation of your W spell. With Kled, however, Skaarl is very important. Skaarl is your ticket into and out of fights (if you ever leave s fight as Kled it better be because you forgot to bring the HAM), part of your survivability, damage, you can't even Ult without her. You can feel the impact of Skaarl's presence in Kled's kit. With Kindred, Wolf is just kinda "eh".
