No point in implementing anything to address this issue, it happens so infrequently and any "fix" would have some obnoxious ramifications. It has happened to me once( since ARR launched) , in Gubal back in HW. Tank and dps hit 60 after the second boss and left. We got replacements and continued on. Wasn't a big deal. I'd much prefer that than them trying to force a vote kick.
If I was to vote for fixing something it would be for addressing players that are horribly bad/lazy (which of course is never going to happen).
