caitlyn is a reactive pick to the meta, nerfing her would disproportionately affect her later
meta adcs
adcs caitlyn does well against
4-5 man ganks bot lane are common
caitlyn works well in an environment with consistent ganking because of her long range and traps
support itemization and peeling champions are extremely powerful at the moment, which also benefits caitlyn (as well as every other carry)
it's like back when rammus and malphite had super high winrates and banrates in diamond when everyone was running 3 marksmen teams. they didn't get nerfed, they simply stopped when 5 ad team comps stopped being a thing
sure, caitlyn might be overtuned when so much of the meta favors her, and some of it might take a while to switch. but it's better to wait and see how she is after all her good matchups arent meta and jungle nonsense is sorted out and make sure she isn't sejuani'd and the list of viable adcs shrinks even more
