The old lore was innovative. Rich on gameplay/story integration and worldbuilding.
Then half a year ago, Riot made a dev blog where they claimed they were retconning everything.
They shortened a bunch of champion bios, and then...
silence.
The part so many of us are upset over, is the fact that we are attached to the high points of the old Lore, the League of Legends which the game is named after, the Institute of War which is the organization maintaining the league, the Noxus-Ionia war and how it was resolved via an actual game. And of course, the Summoners, us, the players, our rune pages, our masteries, or victories on the rift.
They made us part of the world, made the world vibrant, gave it something unique.
And now they want to take all that away because the new guys in charge of narrative doesn't like it.
Personally, I joined late last summer, and was starting to get into the lore barely when the Great Retcon happened.
I'm pissed about it, it tears me up every day, reducing my ability to function.
In part because I don't deal well with having these kinds of experiences removed from me, even if it's currently just a threat to do so, and in part because a game with so deep gameplay/story integration is something I've been wanting for the last 5-6 years...
It doesn't help that a lot of their arguments for the retcon were factually wrong.
As in, they cited the lore and got their facts wrong, in particular their vision of Summoners as all-powerful puppetmasters is disproven in the Journals of Justice, the defunct in-setting newspaper which answered a lot of questions like that.
So that's the deal really, their lore had a big enough crowd following it, and they decided to claim they were gonna screw us over because they wanted less work.
And then didn't follow through on any of it for 6 months.
So currently, we're sitting here waiting for the hammer to fall, and trying to plead as much as we can in the hope that they redecide and keep the story they've shown us intact, as they've seen fit to do after they announced the retcon.
It didn't help their case that all the lore they've released since the announcement fits neatly within the old lore.
