I really am not a fan of games that take away exp. PotD & and HoH are already risky cuz you can spend 30 or so minutes on it only to get no exp if all four party members die to a landmine or something and that's wasted time. In my opinion, people earned that exp by putting their time into it. The first few replies basically already said all that needed to be said. Don't ruin something just because there's the rare "bad egg" who abuses it. Out of the six or so years I've been playing FFXIV, I've only come across one player who dropped out as soon as they got to max cap. Otherwise, the still-rare drop out is usually for valid reasons. (Even if they weren't valid reasons to me, it's not my business.)
