question about knights and armor

[lorddais]

Am I misunderstanding the point of the class? I was to understand that knights could take the most damage because they got to wear the heaviest armor not just because they had constitution and life boosting skills in vanguard,

but it seems that the armor score doesn't make that much of a difference when I can increase my armor score by 80% with a lvl 4 caution and still receive similar damage and reduce an enemies armor by 80% by a lvl 4 taunt and not see much improvement in damage dealt.

Am I imagining this or does anyone else feel the same?
