I explicitly mentioned "pay less per click" so I expected most people to take it as tCPA/tROAS and similar kinds of bidding families? Yeah, technically you're gonna pay less per click even in fCPA, but usually people won't say anything about clicks in fCPA products. It's my bad if it was not clear enough. Anyway this doesn't really change the issue; these kinds of bidding strategies are not really CPA cost type but the result is nearly identical for most campaigns/ad groups. OP's behavior doesn't really affect the amount of advertiser side cost.
