No real point in running 4. Even if you make your character run it efficiently, you are end game at that point and you don't need that extra damage in terms of another herald. At that point you will be getting shaper/elder items that fit your build that exponentially raise your damage beyond what a single skill can, and making your build fit 4 heralds would make all of your items not worth.
Just run 3.
I also tried to run 4, and I got similar dmg output to my build at the time, but I had problems keeping my whirling blades going and could not find a way to increase my damage beyond that point.
This is my Tri BV, still running tabulas. Lvl 90 I have around 5.3k hp and maxed out res.
