Kind of curious but why only three crafting slots. I would figure the higher in the crafting you get, the more slots you would get. Just curious if there is a reason for this that's all..
Probable Short Answer: Timesink
What is a Timesink? A Timesink is something that MMOs and other games use to extend time in game. The Good thing about the Crafting TimeSink is that the counters continue to tick away while not on that wizard, unlike the Elixir timers.
or is it the number of crafting tables you have? ... one per table?
if not i think as a legendary crafter a Crafting slot should be added to the book on every odd crafting level ... on levels 10 ,30, 50 , 70 etc. when you complete the crafting quest for that world.
as we get higher in levels we should also be able to craft more items at each 20 levels as we have passed two crafting levels.
i believe we only have three because if we had too many we will buy a good recipe and get a lot of reagent and craft it over and over again then sell it to the bazaar like me i craft a lot of large ice-cream and sell it for 200-500 and the cost for reagents cost i think about 100-200 in that range so if people did that all day with lots of slots that means people will earn lots of money for doing nothing so there is a reason for three slots and having to wait hopes this helps :) :-) :D
