For those that do not know, the number of supply missions offered daily by your GC equates to one request for every unlocked DoH/L class you have. This means you should immediately unlock every one of these classes, even if you have no intention of actually leveling it the conventional way. Some important notes:

–Turning in an item during a supply quest gives you XP towards the class that produces the item.
–HQ items will give you considerable bonus XP/seals.
–At low levels (1-10), massive excess is listed on the market, making items and even the HQ versions of many items, dirt cheap.

Personally, I have been focusing on GSM, WVR, and MIN, but since I have every class unlocked, I have been able to level almost all of the DoL/DoH classes to at least level 5 in only the time since early access began doing nothing but supply quests…

So, if you want extra seals, or if you want bonus XP for your main DoH/L classes, or if you just want to start leveling other crafts without wasting time actually synthing, it is something to think about…Spread out over months or years, that XP will add up and you never know if/when you will need to make something.
