I just logged on my brute to check (fire/fire) and I can also slot taunt inc into every attack. That being said, pool powers attacks don n't get the effect (where as I imagine tankers ones do). I'd say it;s definitly a power set thing and not an inherant thing.
I geuss brutes are supposed t hold agro to an exctent so our attacks tdo have a slight taunt ability.
Brutes have a gauntlet type effect on a single foe, not 5 foes as tankers do. It basically assures you can hold the agro of a single foe, so there'll be atleast one person to hit you I guess. Makes fighting AV's interesting

Hmm to build fury 
Yup, as Cynic said, Gauntlet has an AoE effect but Brutes can only taunt the mob they are attacking.
Ahh, I see, so the consensus is that a Brutes 'Gauntlet' effect is limited to just the target you're actually pummeling and doesn't generate an AoE taunt against other mobs that are in melee range but not being hit. Sounds reasonable and makes sense. Thanks for all the replies.
Never knew about that, you figured they would make it obvious for you. 
So, I've recently made my first Brute, Super Strength/Invul, and I notice that as well as all the usual enhancement suspects (damage, acc, recharge, KB/disorient and end reduction) all the SS attacks so far also allow taunt duration enhancements to be slotted as well. This surprised me somewhat as I didn't expect it to be the case.
I already have an Invul/SS tanker, and to date I've just assumed that the only reason he could slot taunt duration enhancements on all his attacks was because his inherent Gauntlet power added a taunt component to them in the first place. I also thought the Gauntlet inherent ability was unique to Tankers alone (AFAIK no other AT gets more than one inherent power) Yet my Brute also seems to have it - in addition to his inherent Fury power (at least, I'm assuming his attacks have taunt seeing as I'm I'm allowed to enhance their taunt duration!)
So is Gauntlet/taunt/punchvoke/whatever inherent to the SS powerset irrespective of AT? Or is it just a mistake they made when transferring the SS set over to CoV? Or even something else entirely?
Thanks in advance.
