Shockwave and New Warcries/Fist of War interactions?

If I have this 3-link setup:

Earthquake-shockwave-fist of war

and I use seismic cry, will the shockwave get the benefits of the exertion(and if so, will it use up an exertion charge?)? Also, will the shockwave get the benefit of fist of war support?

From my understanding, both Fist of War and exerted attacks only apply to attacks that you use, which means that triggered attacks like Shockwave will neither benefit from it nor consume an exertion.

Phooey. So the next question then is what's better, shockwave or fist of war? They seem to fill the same niche: amplifying slow attacks.

That will depend on the numbers and what other interactions you have going on. Fist of War seems to affect both the base hit as well as the aftershock of Earthquake hits, so the size of the hit will be considerably larger than that of Shockwave, which makes a difference for stuns and ailments. Also, it will probably be a more modifier, which means it should stack with Ruthless if you line them up.

Otherwise you will need to weigh the cooldown against the actual damage benefit for your build, both of which are impossible to predict at this moment.
