You do realize they're aiming to make a Prestige skin every event? Say good-bye to your life.
How often can we expect to see a Prestige edition skin? I assume they will be more frequent than ultimate skins but less frequent than Hextech releases?

I am Carlos - 8 days ago We haven't decided on this yet, but if is successful I believe at least one per event.
Looking at how much the Season Pass sold, I can already tell you this was successful. Sorry to say, but I think this is the new norm for events.
Ask yourself how many events are a year? Ask yourself if you have time to play four hours a day for over 30 days straight. Welcome to the League of Grinding.
