Im just confuse as a non-native english speaker because growing up and familiarizing myself with the Greek Mythology, it was always pronounced as /zoos/ but casters pronounce it as /zey-yus/. So im wondering how should the greek/top-lane god’s name be pronounced?
The correct reason for the pronunciation is, because he wants it to be pronounced the korean way, which is “Je-woos” which is the reverse of his real name “Woo-je”. This is the real and true reason.
The other reason you mentioned is merely a by-product that makes the life of the casters easier.
