Is this an actual argument, lmao?
The same Boa that went around beating marines left and right
the same Boa that stopped Smoker from beating Luffy
the same Boa that stopped and destroyed the pacifista targeting Luffy
didn't use CoC to help Luffy because she was scared according to you? Lol. Actually using CoC to knock out a couple of marines and what not would be far less suspicious than actually kicking them and fighting them.
Doffy was enjoying the chaos around him, but still didn't even use it once to get rid of some WBP fodders and spread more chaos.
Sengoku actually devised a plan to destroy the WBP from the inside and try to reduce their manpower and cause a disturbance in their rows
but never once thought about using his CoC to get rid of some fodder. Makes no sense.
@comrade explained this already.
