willump / LoR Yetis

https://imgur.com/fSA4Gwq there have been threats critizising willumps design im sure, but has this been talked about? as far as i know riot said LoR = canon. willump and the LoR yetis are clearly not the same species! my guess would be: design team for willump thought the old design to "standart yeti" and decided to give yetis in runterra a more distinct look with the 4 arms. probably not planning on ever depicting other yetis than willump. then the LoR team decided to show more of the different races that have only a champion showing them (yetis, trolls, minotaurs) and didnt want the yetis to be something unfamiliar. makes sense that you want to give the audience what they expect when they think of yeti. since they will neither visually rework willump, nor scratch all the excellent LoR art, it will just be like this and not talked about or get some thin "magic gave willump 4 arms and antlers" explanation.
