Learning curve of playing one shot champs and hyper mobile champs vs defending against them

It is much easier to learn how to abuse hyper mobility, blinking and burst damage then it is to learn how to play against it.

I suppose you could say that moves that are very fast, instant abilities, have a positive benefit for the user that his not the inverse of the negative benefit to who it is directed towards. Meaning, one the receiving end, its much worse because its harder to react to something in an instant than it is to decide to use someone that will take an instant once the decision is made.
