I agree that Approval Voting would probably be an ever better reform than RCV, but I don't think it's quite as simple as you suggest. Implicit in the voting process is deciding what you think "support" means. For some voters, that threshold will be "I like this candidate, just not as much as my top preference" while other voters will set the bar at "I could live with this candidate winning, as they're not quite as bad as the candidate I'm most afraid of". Not only does this mean that different voters are effectively answering different questions, but it means voters may feel overwhelmed or confused (as in The Paradox of Choice, and exponentially more so than picking just one top preference). This also leads to tactical voting, with some politicians or activists telling their supporters to "approve" (or remember not to approve) of some third candidates who they think might gain not enough (or too many) just-in-case votes. Perhaps these concerns aren't a reason not to try implementing it for elections, but I'd feel more confident about it as a voting method once I've seen how it stands up to large scale malicious campaigning, with groups trying to undermine confidence in the process or exploit voters' unfamiliarity with it.
