User blog comment:Sargenttacos115/Why are Sting and Rouge so weak?/@comment-216.171.198.17-20150321025250

There is one thing to consider. Ever notice how every time Natsu goes into dragon force he is never fighting a dragon slayer. I believe that dragon force is a great power up but it makes the powered up person weaker against a dragon slayer who isn't. Think about it both sting and rouge, and Laxus (hasn't been confirmed if the scales on his arms were dragon force or not though)
