You're wrong. Whoever is in last doesn't effect the outcome. They are in last, and are eliminated as if they were never in the race in the first place. Whoever voted for that candidate instead now votes for their #2. This is a good thing: it's a feature, not a bug! The person with the most #1 votes can lose, sure, but that is a positive effect of switching systems.

I think you have a misunderstanding of how ranked choice voting works - check out this short video, it's very helpful and will show why it's a good thing
