"why do you think teams have dedicated igls in the first place"
I can argue the same and say "why do you think teams have dedicated smokes players in the first place" "why do you think teams have dedicated duelists/entry players in the first place" "why do you think teams have dedicated sentinel players in the first place"
idk what you were trying to accomplish by stating that teams look for igls since teams need players to fill every role.
Furthermore, I've been backing up my arguments with facts and reasoning such as bonecold going -42 kill deferential in the last 4 games and the very obvious lack of shotcalling and decisiveness as proven by them failing to qualify past the group stage as the 2nd lowest team in the group. You've been just stating hypotheticals with 'nobody else can probably igl tho even if we don't give them a chance'
