I'm sorry but...
I was omnicrafter in 2.X
I was at the beginning of 3.0
I was stunned by specialist system

but now I really enjoy it !
It bring people together, I mean I made a network of people I know and who love crafting
we help each other, trade comp help and answer question... that's really fun !

It follow what yoshida said about communication and playing with other people (not in a bad way XD)

...

The ONLY annoying point right now is the awful amount of time you have to spend to gather enough comp to make a 2* craft
and I said annoying, not bad or need to be fixed...
It's doable just long

and I think we will later have to said comp in dungeon
in a way as easier as collecting lv50 2* to 3* comp in ilevel 70 to 100 dungeon
