I've earned and used my guild marks to learn crafting abilities. So why when I synthesize, do I only have a choice of 2-3 of the 5 I have assigned? I should be able to choose which one I want when I want it.

Let's say I have Preserve, Maker's Muse, Fulfillment, and Harmonize assigned to my trait bar. I sit down to synth and one time I can choose from Fulfillment or Maker's Muse. What? I have all on my trait bar, so why can't I choose from those 4?

Yes, go ahead and put a recast timer on it. That's fine. But if I have the knowledge, I should be the one deciding when to use what ability, not have it be randomly decided by the game.

Make it like the battle traits. I assign those and can use whichever one I want when I want, as long as I have the necessary TP or the timer has cooled down.

Crafting should be the same.
