Let's look at all 3 of Paladin's 210 swords and compare it to the other two tanks here:

Paladin:
Gordian Blade: Crit+73, Det+49
Hauteclaire: Parry+51, Det+69
Almace: Crit+51, SkS+73

Warrior:
Gordian Axe: Det+68, SkS+102
Parashu: Parry+71, Crit+102
Ukonvasara: Crit+71, Det+97

Dark Knight:
Gordian Greatsword: Parry+102, Det+68
Deathbringer: Crit+71, SkS+102
Nothung: Crit+71, Det+97


So I really don't see the issue here, each tank has a great weapon (for Paladin that is the Gordian Blade), an okay weapon (Almace) and an avoidable weapon (Hauteclaire). Are people really complaining that the anima weapon doesn't have the exact same stats as the A4S weapon, if stats mean that much to you then get a group and progress through A1S to A4S and get yourself that crit det weapon you want, I recommend it.
