Rengar was released in 2012, Jhin less than year ago, yet they both have 2 skins.

Tells enough, huh? Why Rengar can't get a proper skin. He has always been a popular pick. Jhin is out for less than a year, and already has two 1.3k RP skins. All of Rengar skins are simple, they don't even have a special recall animation nor any special effects. What's the problem?

Well, SSW Rengar doesn't count as skin, it's absolutely terrible. I don't get the point of making those LCS team skins.
