Delaying Azir for storyline reasons doesn't seem like a good call to me
I can't find the post now, perhaps it was deleted, but someone from Riot confirmed that the only reason they're not unlocking Azir is so they can put out more Shurima storyline first. I'd just like to let you guys know that I'm pretty much positive most people would just rather be able to use the finished content they already downloaded than to wait a week just to see a new couple minute story video first.
I don't think anyone needs any extra reasons to dislike the story stuff right now :)
Edit: if you're gonna downvote me for not reading surrender@20, thats cool, but you should then upvote the guy who took time to inform me and any others who don't use that site :) Thanks 12tales!
