yeah thats the unfortunate truth about ALL of kabuto's pawns.
off topic- i dont think its fair to bring kabuto into the listings BECAUSE he uses a technique that doesnt actually discharge his own chakra when its active; it uses the living sacrifices body and then replaces the soul and physical features with the dead person. so thats why it probably "has no weaknesses" because it doesnt depleat the users chakra.
more over ,you cant exactly count the new characters like 3rd raikage if your gonna count kabuto, because he supposedly owns them edo tensei right, or you can include kabuto and the new characters but excluding the fact that kabuto can use edo tensei because he is using someone elses power not his own. (hopefully your still following). lastly the technique can potentially be used by ANYONE , even konohamaru if he had the guts to abduct a living ninja and go grave hunting and then learn the procedure, this simple and harmless jutsu cant possibly count as a feet; can you say kabuto is stronger than SO6P if he managed to resurrect even him, i cant. taking impure world resurrection out of kabutos arsenal still makes him in the top ten tho because he has oro's jutsu and DNA and apparently he his both a medical genius and a genius in general.
