Bard swarm kiting or zone disruption?

[Talerain]

I have a question about swarming in Velk. For example, Frenzied group trains entrance and bard picks up all the mobs and starts to snare them around for entrance group rather than causing a wipe or our group from being disrupted. Is it the AOE Damage portion that is causing issues, the repetitive behavior mentioned in CoM or something else?

In the scenario above, I have several options:
Always play snare song run in circles:
1) combine with melee dps buffs to let melee kill faster
2) combine with an aoe DOT and melee dps to slowly kill things and supply group with dmg buffs
3) only play aoe dots while melee kill
4) have person root individually, play aoe dps songs on top of them while they can't hit you while you are no longer swarming but still snaring.

Which of these is bannable?

Keep in mind that it is never the intent to swarm kite in the zone but if shit hits the fan why would it not be considered an option for a "group" to handle it how they deem fit?
