If you know what kind of weapon you'll be getting, it's not that bad to have a few points already spec into the weapon.
But yes, you should hold them off until you get your Warfare maxed or something as that gives you the highest amount of damage. (Warfare is added after Stat and weapon are already added and rounded up)
After that, feel free to start dumping into 2h or dual wielding because the extra stat is huge. Like, you will never be able to compete with 2H when it comes to crit damage because of that +50% crit multiplier and when you consider that crit is one of a later multiplicative factor, that +50% crit damage is going to be HUGE.
