for me it depends on
a) which skills that I could get
b) which attribute the tokens are for
if its example LWT skills..I will most likely be choosing the attribute tokens
if its evade/first aid I would probably choose the skills
if the attribute tokens are for psyche I will most likely be choosing the skills instead
if its intelligence or agility I will go for the attribute tokens
and last but not least it will of course depend on: CAN I GET 100 Tokens for this attribute anytime soon?! If not I will not take them.
