Evasion is a stat that is detrimental for Gladiators. We thrive from getting hit, do not avoid it. Evading does not give you TP, it does not let you Phalanx, Jarring Strike is an off-class ability that we have no other use of the affinity trait for, and shields are tenfold more reliable and available. In the current state of the game there is absolutely no use for an evasion based Gladiator tank.

Haubergeons are for general use outside of tanking HNMs/Tarbh Uisge. Pretty much any moment where you are not spamming your shield rotation or emulating dodore. The STR does not help unless you are using the normal guard ability and spamming Heavy Stab.

Evasion should never even cross your mind when looking at gear.

Ever.
