It might seem that way, but some people just find a zone. 
I fought 4 shielders off yesterday as a polearm user, I died, but I dealt tremendous amounts of damage, so my boys came in and swept up after I was long gone. 
But fighting 4 shielders (3 competent and one random) isn't very easy. But I was in my zone, and did alright. Blockan like a baus. 
So it may seem suspect  sometimes, but most of the time, it's just a capable fighter.
