FYI, for most classes you should just put points into your two primary stats, used for determining melee damage (not sure if it's posted anywhere readily visible, it was in an old patch notes. For ARC, it's PIE and DEX). The exception is the two mage classes: THM should put points in INT and either MND (for magic accuracy) or PIE (For MP). CNJ should put points in MND and VIT.
