It is amazing how few people understand this. An individual player choosing to participate in more or fewer activities in the game has a multiplicative effect. Yet a common response here is to the effect of "if you don't like it, don't play".
I disagree with this change, since I never saw insta-declines of HM FP pops as a big problem, so I don't see the point of it. The only part of LFG I find annoying is accept timeouts, where one person went afk and didn't accept the FP. And this change won't do anything to help that.
Sometimes its not AFK's, it's someone in a WZ seeing if they can finish their match before the Que timer runs out
