Snare their mobs. This works well as a wizard, because your snare hits 4 targets at once and lasts only 75 seconds. Clumps off mobs will peel off, then 75 seconds later, come running at the bard from all directions. If they're low-hitpoint kiting (or hell, even if they're not), only one of them needs to hit and stun them and you've got a dead bard.
Druid/ranger snare has its own advantages. It lasts so long (7 minutes?) that the zone rapidly turns into a minefield of slow moving mobs, like so many zombies.
I've killed a lot of bards in my time. It's better than sex.
Hilariously, even while they're disrupting the zone for everyone else (I've seen situations where the zone is cleared of mobs-- literally cleared), sometimes they'll petition you. But their fun will still be over. You can go ahead and petition them right back if you want-- explain that draining a zone of mobs is zone disruption-- or you can just be satisfied that you've saved the day for everyone else that was trying to-- and has a right to-- use the zone.
