The halberd is cursed; it will drain your stamina if you have it on or in your inventory.
You might have skills you want to save points for when you reach a certain level. Say there are two or three skills you get opened at level 18. If you don't save any points, you'd have to just pick one until you level up again. Also, sometimes you just don't have any skills you really want a point in, and you could save it for a really good skill later on.

Edit: Well done, TheMightyOne, you're too fast for me. <img src="/ubbthreads/images/graemlins/cool.gif" alt="" />
