Depends on what spec and who initiates combat first.
Think this is true with any high burst class. It gets to be a DPS race and someone has a head start.
There was a time when I thought sniper was getting a bit over the top, and I was maining a sniper; but then I play on my other toons and realize that everything has pretty much at least one build that is very good.
That said; stupid or ignorance is hard countered by everything.
