Tanquil Island GvG in under 4 min?

Have anyone a clue how it is possible to do this GvG Event Tranquil Island is doable in unbelievable 3min and 51 secs ??

?? pls ??

Kill mobs as fast as possible, throw the fruits that are dropped on the tree,
Have players with the song kill mobs with mark on it. If hes good enough he can cast 2 songs as once without getting interupted.

have one player always spam song at the tree, this play can be interupted.

there is a small moment non of the adds will spawn, everyone will do the song at the tree

kill the boss asap

congratz with 1500 ilvl you can reach 3 mins and 40seconds.
