It really bothers me that they give neither warning nor timeframe for the maintenance on this game.
I'm in desperate need of Blue Bloom Dragons so I was waiting for the maintenance to be over so I could use my remaining stamina before going to sleep, but when 5am (PST) hit I couldn't wait any longer.
I don't know why it took so damn long in the first place but if I'd at least known it would last until whenever it ended I could have planned accordingly. I like events and all but I also like sleep.
