Does anyone know if there's a fix schedule behind the making of mythical skins? Are they mainly for an event or a theme? Do they follow the grid of one champion from each class (mid/jungle/adc/etc.) or just sorta random?
I'm interested because I'm close to 10 Gemstones but none of the skins appealed to me.
Just whenever Riot feels like it. If you don't see any skins you want right now, you can always hold on to them. (And in case you didn't know, Neo Pax Sivir is also available via gemstones, but after January it will no longer be available.
I think a mythical skin for a support is most likely. We've got already one for Top,Mid,Jungle and ADC.
Sure you can play Annie as a support,but she is meant for midlane and we don't know if Support annie will always be a thing.
