TL;DR in bold
Well, I got the answer, first of all, I hate people who lock in stupid champs or champs the don't play with a lot, so they suck in game, that's not so ok but most people buy runes for their mains, which are mostly carries, do you know why people perfer carries? because most good carries are 6300 IP, like MF and Twitch, but their runes are cheap, let's say the ArPen Quints are 1025 IP, while the 32 HP Quints are 2050, double the price. Mostly all tank runes are double the price, but the champions are cheap themselves, Galio is an exception, but he's banned in pretty much every game. And a lot of people just buy champions and leave runes for later, they want to see the potentials of each champion without waiting a million weeks for the exact champion they want to try out.Really, Riot, tanks are the heart of the whole game in my opinion, we need them in every game, but people can't afford them. And the more types of tanks you play, the more runes (example Galio and Rammus). All runes should be at the price of carry champion runes..Thanks for reading.
