Was asked to give the tank 5 seconds before DPSing

What others have said about the tank building aggro.
In addition, since you mention AK in particular and you are a pugilist, you really don't want to be triggering the tail dive before Anantaboga is in position. An early tail dive risks hitting everyone else.

I haven't leveled monk yet but do you have something like Quelling Strikes or Shroud Of Saints? Something that reduces how much aggro you generate? It's a good idea to pop that at the beginning of the fight.

I don't have anything like that. I usually stay a the side of Anantaboga anyways, only going behind if I know it won't hit anyone, and getting more aggro than the tank has never been a problem for me. It was the first time through with that group and before starting the fight when the suggestion came up.
