It's not entirely true. Grit gives a +20% damage redux, as does Shield Oath, while Defiance gives +20% HP and an increasing parry chance based on Beast Gauge. All of them give enmity boosts, but it's still fairly easy to to maintain enmity with occasional use of the enmity combo and use of threat reduxes on DPS. Tanks in Shire gear in Doma Castle are certainly a problem, but it's also the fact that these tanks are dropping their tank stances because MUH DPS, GOTTA GO FAST.
Keep in mind, too, that starting at Bardam's Mettle, incoming tank damage takes a massive spike up for add pulls, and most tanks either don't know this or willingly ignore this.
