Yeah, because Mei had to be balanced after being given the 2 KG. If it was someone skilled in combat in general, like Zabuza, since he's also from the mist, he would've easily been a S rank. Not to mention that one of the two is also a healer(Yin Release)

Or because Kishimoto didn't give a damn at this point in the story and had to make her special in some form compared to everyone else. No point giving her 2 KG and then 'balancing' her by making her ultimately useless.

Sketcher, just stop getting mad at every template you see dude...
