Yes another swarm kite post

[Boilon]

So... today I witnessed a bard (54) swarm kiting in City of Mist with mobs that included the upper levels and likely everything from moat and in between. He would swarm kite around the arena when there was another few people fighting the goo's in the side houses and possibly the inside arena mobs. Not only this but he had a black reaver in his kite (which I guess didn't get damaged by the Magic dot so it didn't cause him to summon, although honestly would be a bit funny to see this happen).

Over the past 2 hours he has died once or twice, and then this just causes a dispersion of mobs all over the place. Also after a finished kite the black reaver was left and then was left to zone and agro on to others. So at what point is this considered a zone disruption in terms of PnP and or otherwise unscrupulous behaviour?

Looking for an honest answer about this sort of stuff. I honestly have generally 0 problem with this in an outdoor zone or less used areas, but city of mist at around this time, i have NEVER seen this before in City of Mist but maybe I do not spend enough time here. At what point is it allowed to take mobs off his train because he is monopolizing a lot of the mobs for people 50+ .

I heard that there was a GM comment or something relating to bard trains and that it was okay to take mobs off their trains to kill despite them having the 'FTE'. Any possible serious replies to what can/should be done in this situation would be great! As much as I want to call the bard out by name, I don't know if that would devolve this in to an RnF , but I ended up logging my monk because i was like fuck it im not dealing with this.
