I joined when Zyra was released, so i'm not that old of a player. But I constantly assume 
and 
are basically the same champ. Junglers, both start with E, I don't play either, always seem fun.
Who do you confuse for no good reason?

Dolasaur1 votesDiana and Kha'Zix when they're both purple. Also Project Ashe and... I actually can't remember who I confuse her for, but I think it's Shyvana or one of the Fiora skins.
When I first started playing, I mixed up Sejuani and Shyvana - both long S names for champs that were incredibly tanky.
RookPusher1 votesoh god, Project Ashe looks like DJ Sona to me so badly. It drives me nuts.
