Here's a new concept: Let's make some Prestige skins and make them ultra rare! We'll only release one every 3rd week.
Seriously though, there have been as many Prestige skins released in 4 months as ultimate skins in 8 years. Doesn't that take away the point of making them "Prestige"?
November: Prestige Kai'Sa
December: Prestige Akali
January: Prestige Aatrox, Prestige Vayne
February: Prestige Ahri
Like come on Riot, slow down a little, can't keep up with the pace of these very rare skins..
