Just played a game. AD Ekko works?

Second vid, that was not a one-shot. Just Jinx being dumb. Ekko's ult at level 18 does 500+(APx1.3) magic damage. Ekko was full build at that point as well. Luden Echo, Rabaddon's, Zhonyas, Lichbane, Void Staff, and pen boots. So we're talking several hundred AP. Because she walked right into his Q, she had 2 stacks of resonance already. So not only did she take both Q hits and his ult, but also all the damage from his passive (15+(12x18)+(APx.7). She would have had almost no MR left because of all the reductions and pen. Jinx never had a chance.

First vid, since the items aren't shown, there's really no way to know wtf that was about except Morg had 2 stacks of resonance and took an E to the face while being 3 levels below Ekko. None of Ekko's abilities scale with AD. So..... not seeing how that could happen unless he got a lucky crit with a full IE build or something and morg had absolutely no armor/MR or HP at all.
