Characters in the new lore
With the retcon still going on I'd like to talk about Riots trend of changing characters. If you want to talk about the removal of summoners and the IoW, there's plenty of other threads where that is appropriate and where I will be at.
First of all, lets settle that characters got changed. Trundle and Xerath are the ones I am comfortable with using as arguments here. I won't go in too deep in the OP here, but I'll give some minimal evidence in that new Trundle is power-hungry and Xerath got his main motivation and modus operandi changed. I am happy to delve deeper into this in the comments below. They got their character changed with little warning too. One day, new lore for them came out and the old characters were gone. Trundle entirely so, never again will I hear a story about the leprous troll or be able to buy his skins or merchandise from Riot.
Why is it relevant that characters are getting changed? In order to write a compelling story, you have to make your readers invested in your story. You have to make them emotionally attached to characters, whether they hate or adore them is irrelevant. If you don't manage that, you will not be able to make an engaging story.
However, I know that any character might just be changed tomorrow, for this is what happened to Trundle and Xerath. This prevents me from getting emotionally attached to new characters, for I know that if I do, Riot might just delete them and abruptly sever my emotional attachment again. The trust between me and Riot is gone in this aspect. It hurt to see that Trundle was suddenly gone, hurt enough for me to be still here on these forums in some kind of vain hope after more than a year. Sadly, it'll only be until Riot finally gets their things in order and makes definite these for me incomprehensible changes.
To conclude: Given this reasoning, I do not understand why Riot insists on changing characters. In my eyes, it systematically interrupt the capability to make your readers care about your characters and engage in your stories.
If you disagree with my reasoning, I'd love to see where I went wrong. The main assumption I made was that Riot wants to create engaging stories, but this seems reasonable to me.
Worst thing is, the new Trundle has been around long enough to probably have fans. I can't call the new Trundle better or worse either, he simply is a different character. Asking Riot to revert the character change would be hypocritical. This only complicates the entire thing. Personally I think one of the Trundles should've been a new champion in the first place and now should still be. Xerath could probably be rewritten to be the same character in a different setting: Focus on his skill in magic, not his skill in politics. Use his old wish to become one with his magic and reuse it; make him wish for true ascension which Azir seems to deny him. I'm no writer and I don't intend to lecture professionals on how to write, I simply wonder why playable characters are getting changed.
I'm not exactly picky on who responds, though I'm curious if this is the kind of thing appropriate for the great parrot IronStylus, who has some honestly curious comments about being approachable for lore things too. The narrative department is going through a lot of reorganisating supposedly and their communication is barely better than half a year ago (Jaredan seems to be trying right now?), so I won't get my hopes up for an appropriate Rioter responding anyway.
Edit: Seems to be a slight bit of confusion here: for Trundle, I'm not complaining about him getting a new body/setting/story, I'm complaining about the one getting the body/setting/story not being Trundle
