[2019] With Arcade Kai'sa, Kai'sa now averages a new skin roughly every 3 months

With Arcade Kai'sa expected to be released on the 25th and Kai'sa having been released on the 7th of March, 2018, Kai'sa now blows every other character out of the water with an average of a new skin every 95 days.

Runner ups include:

• Pyke: a new skin every 131 days
• Rakan: new skin every 194 days
• Jhin: new skin every 224 days (fourth place, as it should)

Just a fun little metric.
