If she was "nothing" without armor, how did she defeat the many adult guards at the age of 11 before her magic awakened? How did she defeat several mages right at the moment her magic did awaken (without having access to any magic weapons and armor)? How did she knock out Sho, while her magic was sealed?

Or even better: If she's "nothing" without armor, how comes that she defeated Ikaruga, Evergreen, Azuma and Kagura without wearing any armor?

When Erza said she was weak, I'm pretty sure she meant mentally and/or emotionally, not physically or magically. She also said at least twice that Natsu is stronger than her and once that she's not sure whether she could beat him, both of which is obviously not the case. This self-depriciation is just a quirk of her personality, that makes her think of herself as weak at times, but that doesn't make those comments true.
