Not to sound shallow, but what kind of DPS will I be putting out with a brawler? Like Adrastus said, I can fluff the gauntlets as fists. Still what matters is not that the fists are equipped or not, so long as the action is going to be fist-based.
Oh and yes, this will be a Warforged.
Honestly, brawler DPS is pretty poor (especially for a Fighter). Spiked gauntlets are only +2 prof with d6 damage (Brutal Brawler increases this to d8). But damage isn't really the point of the Brawler build; it's really about a kind of melee "control". You'll have numerous attacks which auto-grab on a hit, some inescapable grabs, and forced movement like crazy. Your DPS comes from grabbing monsters and shoving them into the Rogue's dagger.
Another note: the build suggests Dex secondary, but you don't really have to do it. You can stay with Combat Superiority instead of Combat Agility, and plenty of brawler powers don't use Dex.
