Hypothetical/theorycrafting question: A champion with no offensive abilities that scales off AD
I had a very nebulous idea for a champion awhile back — no flavor or character or anything yet, but something I thought was an interesting mechanical idea, though I'm not sure if it would work.
I was thinking, what if you had a champion — I assumed a support, though it could very well be some sort of utility marksman like Kalista — with a purely defensive kit? A shield, a heal (tentatively; see: nebulous), maybe a bit of CC and ally-buffing. No offensive abilities, BUT all their abilities scaled with AD instead of AP (I didn't consider things like bonus health or armor, but that could be interesting to play with).
It's entirely possible there's no way this would ever work. We've already seen how Riven's AD-scaling shield (among other things) has caused some balancing trouble. I know Leona's seen a bit of play here and there as a full tank with some AD mixed in, since her AP ratios are abysmal, but in this case I didn't have any real concept for if the character would be tanky, or an AD caster, or what.
Given how little detail I really have, people may not be able to have a solid discussion. But I'd love to hear any thoughts you might have, whether you think it's an interesting theory worth exploring further or that it's horribly broken and boring and that I'm a moron.
