Irelia's passive mentions "Number's Advantage". Apostophe shouldn't be there. A better term would be "Numerical Superiority".
While I'm on the subject of grammar, spelling and punctuation:
Ashe says "...shouldn't confuse mercy for weakness." We don't confuse something "for" something else, we confuse it "with" something else, so that's the wrong preposition.
Number is the subject. Advantage is the modifier. The apostrophe is showing Number's possession of Advantage, denoting that Number gains the advantage, as Irelia's passive tenacity is determined by the number of champions around her, friend and foe.
Also. The VO you are "attempting" to "correct" is already correct. You do confuse for. "It seems I mistook you for a general, not a soldier." "You cannot mistake a dog for a cat."
Edit: Oh! This is also not a bug.
I never heard "confuse for" before Ashe. Cursory search turns up mostly "with". You're wrong on that one, as far as I can tell.
Numerical advantage is still a better way to say it, and again, a cursory search for "numbers advantage" doesn't turn it up with apostrophes. Again I don't believe you. Get me some decent sources on these things.
