Champion bios - Shurima retcons

The sun has set, the epilogue is out, the Shurima event is over. I think now is a fair time to start discussing the lore retcons made in it.

The Shuriman event told one story, the story of Sivir and Cassiopeia reawakening Azir and the city of Shurima. As far as I saw, the retconned champions of this story, Sivir and Cassiopeia, have their identity quite intact. They did what would be expected of their characters in that situation. However, a lot more champions had their lore reduced to minimal amounts.

These minimalistic pieces of lore are supposed to wrap the identity of these champions in a single sentence. I think these are mostly consistent with their old lore (yes, even Skarner, his identity is unchanged, he lost his awesome backstory), save for Xerath:

Powerful beyond reckoning, the ascended being known as Xerath was once a mortal of flesh and blood. He is now something vastly different - a being of writhing arcane energy. Having emerged from millennia-spanning imprisonment, he is now ready to unleash his power upon Runeterra, and utterly destroy any who oppose him.

This does not sound like the Xerath of the old lore, whom merely looked for ultimate mastery of magic rather than unleashing his power upon Runeterra. We also only have perspectives in which his ascension is portrayed as an evil act of evil, rather than an act of desperate obsession over magic. Of course, the latter is easily solved by giving us the other perspective, but why would Xerath seek to unleash his power upon anyone but Azir/Nasus? Why doesn't he prioritize breaking free from his sarcophagus above all else?

I understand Runeterra is a big world and going over each faction thoroughly and telling all storythreads is less interesting than cycling over all the factions telling a single thread of story in each and return in the next cycle. However, I think we have the right as players to know what the champion we're playing is like. I think we should be told what a champion we love and main their identity is without a grand plot twist like "he was like this all along despite his short bio stating the exact opposite". Plot twists are fine by me, but identity twists in a game where you bond with the character less so. ** What I'm asking here is for Xeraths bio to describe someone who is utterly consumed by his obsession for magic and not someone who simply wishes to watch the world burn** (that's Brand). I don't think the current mini-bio describes who Xerath was in his old lore and I hope it can/will get changed.

I hope I brought my arguments clearly and I'll be glad to discuss any of these points. Also happy to see there's a story board now.

P.S. I've also repeatedly questioned Trundle and will remain to do so. For Trundle was one of my favorite champions but his retcon is now withholding me from investing wholly in the new lore (if you think it's the same Trundle: Check old lore+judgement, listen to current in-game presentation, mainly voice-over). I don't care he's an ice troll, I care it's not Trundle. Unless Trundle becomes Trundle again I'll have to force myself to remain cynical towards the new lore and not invest too much into it, for it could all be tossed aside next retconning.
