But what happens if C gets one more of B's first-rank votes?
Then B is eliminated first. And if at least 2 of B's 5 supporters have A as their second choice, A wins. Which, as was said under plurality, would be a terrible unfairness, because no voters opinion on A-vs-B has changed!
IRV doesn't eliminate spoilers; it just makes them a little less likely.
But approval voting and score voting have no spoilers in three candidate elections.
