Recent new champion designs
I believe that the last handful of new champions release reek of a company who's designers are trying too hard to be creative. Kled, Talia, illaoi, Sol, Kindred...
Honestly, doesn't it seem like these champions are weird and odd just for the sake of being weird and odd?
Other champions resonate with me---hecarim brings ideas of headless horsemen and halloween nightmares...shaco, a nightmare jester, the stuff of bad dreams...blitzcrank reminds me of Robo from Chrono Trigger and other alternative technology steam powered type robots...Annie, the quintessential nightmare child...Ezreal, a very final fantasyish sexually ambiguous adventurer.
I could go on and on on.
The point is that a well designed champion will thematically resonate with the players, who will feel or grow and affinity for them.
I feel nothing for the recent champions. I think their concepts were conceived by designers who are out of ideas and grasping at straws.
