I went with Weaver, Leatherwoker, and Goldsmithing myself, mainly cause I seem to get a ton of those items most of the time (main summoner/sch). I've been treating desyth more as a way to just get a ton of extra materials / crystals so far though.

I know an all 60 crafter who did 80 points in everything, for some reason or another. I do know if you ever change your mind, you can reset them back to 1 point if you wanted to respend them elsewhere.
