I actually craft/enchant quite a bit.
I would say the soulcraft rate is very good. (ever since the complaint and extra boost)
The enchant rate during the event (armor and weapon) is very good from 1 -> 15.
The rate from 16 -> 20 though is much worse than without the event.
This is my experience from making many items. (The number is in the double digits, the amount of items I have made)
If you want to know the average of IS/RIS used for crafting or enchanting, just pm me in game.
I suggest making everything legend +15 (well I guess you can only go with weapon now, at least the enchanting part, if you want to take advantage of the event) and wait till after the event to go from 16 -> 20.
Just my two cents. Take it as you will.
