I watched the video where Travis was learning support with Muffinqt, and found out that some skins could affect gameplay. for example, Frost Queen Janna's shield glows with a blue hue, which makes it obvious compared to her other skins' shield where it is transparent. same thing happens with Full Metal Rammus' shield being bloody obvious. I've even heard that Urfrider Corki has a longer animation on his ult. Can anyone give other examples?
