So who do you think is innovating and developing a meta for people to react to?
It tends to be the best players in the game who develop the meta, and a lot of it is, in fact, thinking creatively, be it through an unorthodox build that then becomes the strongest meta build (tank Ekko, and most recently Youmuu's/Black Cleaver Lucian), or from using champions in ways Riot didn't really intend (once again, top lane tank Ekko, as well as bruiser Yi).
Your words are contradictory and meaningless. They are reactionaries toward the game? That means that someone, somewhere, is being proactive in making a new meta, or at least developing the current one.
