Do you have the [item]Jungle Stompers[/item] from Nalorakk? They are much better for threat than your current [item]Boots of Elusion[/item]? They also have more armor and stamina, just less avoidance. If you get Jungle Stompers I would use them over [item]Boots of Elusion[/item] in nearly all situations. (The Elusion have significant avoidance which you may want for some fights)
Yes, [item]Bonefist Gauntlets[/item] would be better than [item]Warbringer Handguards[/item] for threat. They also have more armor and stamina. They only have less avoidance. If you get Bonefist I would use them over t4 in nearly all situations.
Are you interested in high threat for bosses...trash..? And are DPS'ers getting threat capped with you tanking? If not don't worry about it...Ferals can put out some nasty TPS...don't feel inadequate compared to them, they can't do some things we can (heh...like anything involving a Shield).
