Do remember that you have a limited amount of these, since once you get them for each Job, there are no more to obtain. Likely not a huge deal since many of the class/job stats that raise auto-attack damage are typically also the ones you want maxed anyway (MRD/WAR, STR/VIT, so easy), and the system of reallocation may be changing in 2.0 altogether.

It's just something to remember for now, if you are going to be pursuing research.
