I'm a bit lost on privateer companions, they have much higher base will than they have base strength but if they are using swords to attack with and they don't really do anything else shouldn't we be upping their strength rather than their will when it comes to their chances of getting critical hits?

Currently raising up a privateer and I hate the companions it gets as its main boost is will orientated and very few companions are benifitted from will boosting. Even the privateer companions are better off with their strength being boosted rather than their will. Normally I would like to put companions I can't boost into storage (if I could I certainly would) but the privateer doesn't seem to get anything that goes along with it outside of witchdoctor companions.
