In League of Legends (Mostly in the lore) there are multiple different cities, all with different levels of technology.
Some champions use guns, some use swords, others magic.
Just how prevalent is technology in League of Legends? It seems as though in any rational scenario a gun or magic would defeat blades, yet the characters ignore technology coming from places such as Zaun or Piltover. Is this because they would not know of it, choose not to use it, or plain think a good old stick n' shield is better? What would prevent some of the more advanced cities from taking over the other ones with weapons of advanced power?
What stops technology from being an end-all in League of Legends?
