I think someone from riot answered about why volibear switched alliance and on Trynd's lore, if he was switched to Sejuani, then King Tryndamere wouldn't be lore wise and also Trynd's alliance to ashe is connected to Gragas's alliance to ashe aswell.

But I do agree that some of these lore changes are not really needed, it is not in my perspective though, but I think how riot incorporated the champion's skills/abilities/appearance being influenced/talked about in the lore are kinda cool. Like Ashe's frost shot, Trynd's Rage as resource, Gragas's Ult.
