how does teemo not deserve a nerf or rework

look at That Muffin Man teemo build and items and explain to me how come teemo hasnt been nerfed, changed or reworked. Riot games you dont like champions that builds a weird set of items and so to fix that you rework/change/nerf them so how come little teemo has been majorly changed except his ult visual, and passive. explain to me after seeing his build why teemo does not deserve a change at least a rework. he literally build attack speed, ap, ad, health, and MR items that have little or no combination with each other.
