Riot, Summoners were not Gods
The recent lore retcon within Runeterra has really disappointed me.
Back in the day, Riot created lore that depicted an interesting world with summoners and the Institute of Justice and now, for some reason, they decided to retcon the world they exist in (Runeterra) into something much more generic.
What helped to make these champion's themes unique was their placement within the League of Legends, a place where champions from a variety of backgrounds battled one another to determine the fate of the world. This concept has been scratched.
None of the stories that were made recently (the Shurima event, and arguably the Freljiord event) would have been affected by Summoners or the IoW existing or not. There's no clear reason why they needed them gone.
There really doesn't seem like there is any reason to retcon the lore, other than to simplify things for the players that don't care about lore.
Another thing, I've seen too many Rioters misrepresent LoL's lore and pretend that Summoners and the IoW were too powerful, and say that is was the reason that they were removed.
Summoners were never all powerful, all good, or all knowing. **They weren't gods. The Journal of Justice gave us stories that showed us that summoners in lore, were just like us. They were corrupt, self serving, and sometimes bad. **
Riot Please, don't pretend that Summoners and the IoW were all powerful and use it as an excuse to pretend they never existed.
If you want to get rid of them, have the balls to do it through storytelling, rather than retcons.
Or, you could just reconsider your decisions to get rid of them.
Being a champion means nothing, without taking into account the world they live in. Telling stories purely through champions doesn't give us the full picture. We want to see things through the average denizen of Runettera, through its summoners, *and *through its champions.
And sometimes, even through Runeterra's history books.
In my opinion, Riot's newest approach at lore seems much more limiting than what it had before.
,but there is no reason why Zilean wouldn't help them to stop any act of war like this again(and the question is if they still need him or if they had the ability to do it on their own after learning how its done) and while it was difficult to do,there is no reason they couldn't do it again.
destroyed a whole village that was far away by accident and he was just a novice.So it should be possible for a trained summoner to do the same on purpose.
