@Riot , about skins nowadays...
BE FOREWARNED. THIS IS A LONG POST. I DIDN'T MENTION EVERY CHAMPION THAT HAS THESE ISSUES AT HAND. PLEASE DON'T GROAN AND COMPLAIN.
I know that first and foremost, Riot is a business. And businesses have to make money. When it comes to skins, though, it's so blatantly obvious that Riot seems to care about certain flavor-of-the-month champs, while completely neglecting other champs for upwards of 3-5 years.
-Draven gets a skin in June 2015, and then two skins in 2016 in a 2-month period. -Cassiopeia hasn't gotten a skin since February 2013.
-Kindred is getting a skin in this upcoming patch, and she just came out in October. -Kennen had to wait almost 5 years (Arctic Ops on December 2011) for a skin.
-Gnar is a relatively new champion (came out in 2014) who's already gotten 2 skins in 2015, and is up for another skin on the PBE right now. -Swain hasn't gotten a skin since 2012. ** I know he's "up for a rework", but people have been asking for a Dragonmaster Swain skin since 2012 or so, and Riot's been ignoring them completely. Seeing as how it took so long for Yorick to get onto the update list and Ryze is going to be up there for the 15th time or something, I don't see this being a valid excuse anymore**
-Dr. Mundo got a skin in June of last year, and another one's in the PBE right now. -Viktor hasn't gotten a skin in almost 3 years (October 2013).
Now, of course, there are probably other champions I didn't think of off the top of my head, but my point still stands: Riot seems to only care about SOME of the players. They'll keep giving certain champions (Annie, Braum, Draven, etc) skins while looking the other way when people that DON'T pick flavor-of-the-month champions say "Hey, mind looking at these concepts? We'd think they'd be rather cool!" Riot seems to adhere to certain players instead of branching out and getting satisfied consumers and customers from other champions.
For example: Draven gets a skin. Cool. Draven players will buy it. But what if a cool concept like... Like this one really cool and well thought-out concept of Arcade Viktor I found came out? http://the-glorious-evolution-fanart.tumblr.com/post/143938809776/the-glorious-evolution-fanart-updated-arcade (Credit goes to http://the-glorious-evolution-fanart.tumblr.com/ because no one wants to be like Pididly.)
Not only would people be like "Whoa! That looks neat!" or "Viktor hasn't gotten a skin in a long time and this one looks so cool, I wanna instabuy it," they'll also be like "Viktor? Who's THAT? Maybe I should cough up a little RP and test him out! I don't see him that much!" So, potentially, there will be a ton of revenue instead of the stagnant revenue from an already popular champion with plenty of recent skins!
TLDR: Riot, when making skins, please pay attention to champs other than the flavor-of-the-month or popular ones. Other champs need and deserve love too.
