It's really up to you. I personally prefer more balanced stats so that smaller people can't hit me so easily in war.
If your looking for a pur build of strength or intel I would go intel more farms for that make more money but up to u
You make same regardless of your intel. Plunder goes by crew members an levels. Either go balanced if yo system war alot as riccena said. I prefer heavy strength build. Better for strip farm wars. It's all preference. Depending on how you play.
