I know this is going to come as a shock, but the Riven patch has been officially delayed by 24 hours. It remains unclear what caused the delay, whether or not this will affect the end of Season One (though I would bet it will), and whether or not there’s a plan in place if ELOs decay tomorrow.
Here’s the official quote from RiotRara in a post made late Monday night/early Tuesday morning:
Our release team has confirmed that an extra 24 hours is needed to ensure quality release. There will be no downtime tonight for the Riven patch. We are sorry for any inconvenience and thank you for your patience.
Needless to say the forums are displeased, as I think they have every right to be. This is incredibly late notice for what was supposed to be a substantial patch. Hopefully we’ll hear more from Riot tomorrow.
