hmmm, maybe you need one or two more holds there, it's what makes a dominator own in PvP, in my opinion this looks more like a build for PvE, and because you're so squishy as a dominator you don't to be at the front hailing your opponent with attack, apart from that good job.
Hey there, just a couple of points (although I'm not exactly a hard-core PvPer, so take them with a grain of salt 
)
1. It's gonna be difficult to stack Holds on people with no Hold SOs in Char 
2. There was some testing done over in the U.S that suggested that Blaze (Lv 38 secondary power) was actually one of /Fire's toggle droppers. It's also one of your highest damaging powers in your secondary, if not THE most damaging power in it. Why haven't you taken it?
That's all I can think of right now
Agreed, your build is offensive after all.

I'm also planning on having the following Epics:
Scorpion Shield: Black Scorpions technologies are impressive indeed. This energy shield grants you Defense to Lethal, Smashing and Energy attacks, as well as improves your Damage Resistance to Toxic damage.
Disruptor Blast: Fires a tremendous charge of kinetic energy from your Bane Mace. This charge is so powerful it will explode on impact, blasting all nearby foes. Some affected foes may be knocked down by the force of the blast. You must have one other Mace Mastery power before selecting this power.
Summon Tarantula: Black Scorpion will grant you a Toxic Tarantula to command. Weaver One developed the Tarantula Exoskeleton Armor, which so radically transforms an Arachnos troop that hardly anything human is recognizable.
Slotting the shield for defs should stack nicely with CJ and Maneuvers, yes the %s are small, but together they'll help keep my [censored] alive in PvP
