@Meddler: Should we have some more straightforward Champions in the near future?
Rek'Sai, Bard and Ekko can come across as kinda complicated. As Rek'Sai, you gotta know how to manage your tunnels well and be well-versed in jungling; as Bard you need to know when you can safely roam so your teammate doesn't get slaughtered. And Ekko... yeah, no explanation needed.
Lately we haven't had any Champions that are relatively simple. Perhaps Riot hates "simple and boring" designs, but it works for Garen, Annie, Nunu, etc. Is there a possibility that one of your next Champions in the development pipe could be more down-to-earth?
If you need an example of "simple", here's one to check out:
