Provoke underwhelming?

[Megido]

It gives top enmity +1.

So it can be possible for the one tanking to grab aggro with auto attack in between 2nd tanks provoke -> highest enmity attack, alone.
This can also be remedied some by simply facing away from the boss for a second, so that you wont auto attack right after the provoke. Though im not sure but i assume you cant parry attacks when not facing the boss, so it has to be done quickly, say right after death sentence but making sure a plummet wont hit right after. You yourself could pop a Fight or Flight or Berserk at a tank switch point, boosting your enmity.

Obviously our ranged pulls work very well in tandem with provoke too.
