Hammer build: need feedback + question

Hey all, I made this hammer build for my warrior:

Strength: 9+1
Hammer Mastery: 12+1+3
Shadow Arts: 9

[skill]Flail[/skill][skill]Devastating Hammer[/skill][skill]Crushing Blow[/skill][skill]Heavy Blow[/skill][skill]Shadow Refuge[/skill][skill]Way of the Fox[/skill][skill]"For Great Justice!"[/skill][skill]Enraging Charge[/skill]
(plz note that the pictures are not up to date and FGJ and Shadow Refuge have been buffed well since)

I use this build for AB and PvE and I would like some feedback on it

And I also have a question, sometimes I want to do some RA, but this build has a few issues there:

1) Flail is self-snare. This build is now just managable energy-wise, but if I put another IAS in the place for flail I fear I will get energy problems because as far as I know all other IAS need 5e to cast. I dont want to be forced to wear gladiator insignas

2) No rez sig, in RA this skill is pretty much a must but I dont know where to fit it in because I dont want to loose any of the 8 skills I got now

hopefully you guys can give me some advise on this

regards

For RA just change up a few things.

Take out Shadow refuge for Rush so you wont get caught in flail so much.

and drop way of the fox or For Great justice for a res sig.

the general hammer bar I run is something like:

Dev. Hammer, Crushing blow, hammer bash, bulls strike, flail, rush, enraging charge, res sig

What that guy said.

Barring the Heavy versus Bash pros and cons.

yeah heavy vs hammer bash is usually just Preference. I tend to lead toward hammer bash just because I like the unconditional KD. Idk why i just do lol.
