Why?

Why in the world did Riot ever go from story telling like this...

In the ancient civilization of Shurima, the mage called Xerath practiced magic with undying passion. He believed that with enough magical power, he could gaze into the heart of Runeterra to know the secrets of history and the universe beyond. Such magic was beyond the limitations of a mortal body, but Xerath obsessively pursued a path to infinite power nonetheless. With every breakthrough he grew more and more powerful, yet not without consequence. Xerath's increasing arcane abilities wrought havoc on his physical form. Desperate, he undertook a dangerous ritual to transcend his dying body. The outcome would be immortality or self-destruction. Violent magic unleashed during the ritual caused devastation throughout Shurima, but when the dust settled, Xerath emerged as an ascended being of pure arcane energy.

Free of flesh and bone, Xerath held nearly infinite power at his command. However, in the wake of his chaotic ritual, the mages of Shurima feared his careless disregard for life would bring ruin to the kingdom. After a terrible struggle they subdued Xerath, but they could not destroy his ascended form. Instead they trapped him within an enchanted sarcophagus and sealed him in an underground tomb. Eons passed, civilizations rose and fell, and Xerath's imprisonment was lost to memory. For centuries, Xerath's vast power tore away at the sarcophagus and weakened its spell. Finally, he willed forth a burst of magic that shattered his prison, but its core remained, containing Xerath and his power within its broken pieces. Seeking to rid himself of this burden, he was drawn to the magic of Valoran's nexuses and found he could absorb their power. Yet the nexuses had gatekeepers: petty mages known as summoners. Xerath knew his key to true freedom from his prison lay in gaining their trust, and he offered his power to the League of Legends.

... to this?

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.

The old lore speaks of a man with desires, ambitions, and struggles who sacrificed his own humanity for sheer arcane goodness. He's a character. New lore says Xerath's a pretty strong mage.

Yeah, the Azir/Xerath story they put out a few months ago gave him a few emotions but the whole thing just.... never felt like Xerath to me. The new, story-Xerath can be boiled down into a jealous, revenge-driven mage. In and of itself that's not so bad a character. Honest. But is that supposed to be... Xerath? Our Xerath? And to be fair, I haven't read recent lore too much because of the awful press it gets with the community. I gave it a run for the first time in awhile thinking, "The League community loves to overreact at everything... can't be that bad!" Boy, was I severely disappointed and to be quite frank, upset.

I'm not upset that they abbreviated his lore. The abbreviated lore, while being a watered down version of his old (better) lore still says that Xerath Ascended into awesomeness and is pretty pissed at being imprisoned. But the story just missed the mark on... everything else it feels like.

What happened? O.O
