@PugMaster, just wondering did you read the linked article, it kind of explains it.
And I would have to say there really wasn't any lore to destroy, of the lore backgrounds I read many of them were boring and I didn't find them interesting, I never quite understood what the game play had to do much with the lore anyway, and out of most heroes I think the original trundle lore was the most interesting... most of the lore consists of "No one knows where they came from...but they like to kill stuff" or "One day decided," which isn't very solid... and in that article Pharaoh_ linked it explains how they are setting LoL up for more of a narrative so it can possibly translate to a movie or TV series, which, with all the new short films riot has been making, could be a very valid possibility.
I for one am very happy with the decision to overhaul, of course that is just my personal opinion, any thoughts?
EDIT: Today the update changed the Azir loading screen which was there for... 3 days maybe... Azir facetime is less than Gnar's xD
EDITEDIT: Azir's first skin is quite good, i'm really liking Galactic Azir
