Feeling outplayed and being outplayed are two radically different things.
Sure you might "feel" liek you got outplayed by Ahri because she did some fancy dodging and kited you hard, but did she really outplay you that much? It's really not that hard to land a charm, Q, and then run in a circle with your ult. Sure you might "feel" like zed just facerolled on you in a teamfight, but have you tried facing rolling someone with zed? It's not as easy as it looks.
this is not exclusive to these champions. Both of these champions can totally outplay someone or can totally get a kill off of just a faceroll, but people need to differentiate when they got outplayed vs felt outplayed.
