In rated play, as soon as they use offensive cooldowns they will get rooted, stunned, cloned, etc until those cooldowns are over. Same general thing can be applied to arena where at lower ratings it is easy to dominate as a DH, fury, frost DK, etc because you just get to open on people without recourse. In higher rated play, you get shut down with something as simple as a root.
Then there is the skill level of the warrior. Just because they are a warrior does not mean they understand how to use their abilities effectively, how to be in the right position, which target is weak, etc.
Essentially all things are not equal as you suggest between unrated and rated play. All things are not equal between low rated and high rated play either. All things are not equal between some team compositions of the opponent and the warrior.
