Early game defensive options.
So it just came to my attention that early game defensive options are meaningless to certain champions.
Kata, Teemo, LB, Akali, I dont know of any other champions that get to do this but.
In short, if they see you getting MR against them early on (aka abyssal mask) they can opt into the other side of the gunblade or whatever teemo's build nowadays.
Running anything with adaptive damage means that they deal bonus Physical damage even though all of their abilities are magic damage. I'm not saying that this is that big of a issue. But its part of the early game power creep for these champions. Because everyone knows that Kata and Akali are actual problems right now. They aren't super massive problems tbh. But they are problems none the less.
