I wish they'd be a little more lax with the DF penalty to begin with. If i have to drop due to unfortunate circumstances (keep wiping or DPS goes afk for free tomes) i shouldn't be penalized for the FIRST time I drop group. maybe not even the second, but for the third. Hell, even make it a 30 minute lockout i don't care. Sick of being penalized for one time for reasons that aren't my fault. 15 minute penalty because I was being harassed in a dungeon and decided to leave? Yeah, give me the penalty while the harassing party gets away with it free of the lockout timer.
