Sorry but I find it hard to believe that the quiet, silent, planning ones ever get any far no matter how quiet and how much planning they do when going against things that already overpowered them once when going alone.

[Everyone can have each their own plans and ideas, but if they pretend to carry them on on their own or with just a small bunch of people? Now then is when Bulma doubts they will manage anything, but she supposes people just deny the fact that they were once overpowered easily by claiming that them being brought here was a surprise attack or whatever.]
