I apologize if I offended you.
Have you ever considered that perhaps playing the class as you so self-righteously suggested is not very efficient?
Or maybe everyone has a different play style, if you want to play a juggernaut who wields all plate and a giant impaler and solely depends on ONE stamina bar, by all means satisfy your ego. But if I find more utility out of the dragon knight with a destro staff & some fire DoT damage spells and crowd control, who are you to say how I assign my character his/her role?
And to answer your OP, you will not be disappointed if you choose to play a "pure warrior".
