I only leveled all my crafters b/c my FC is a bunch of lazy fluffs and dont properly work on Workshop stuff. Personally i can't stand the crafting system in this game. Granted it's different by a long shot from any MMO i have ever played but my main issues are this.

Why (just like Gathering classes) is Ironworks an 100% OVERMELDED MUST to make some items yet it's Lower Ilevel to Augmented Scrip gear? That to me is just illogical at the max.

A issue im hopping is going to be fixed the same way the actual fighting classes are is Cross Class abilities. Though it doesnt matter all that much now that i'm lvl 60 in everything anyways.

My bigger issue is the amount of RNG that is put in to crafting. If RNG dictates i can completely fail trying to make an iron ingot wearing full overmelded Ironworks. If nothing else Ilevel for gear in crafting should make it so you have less chance to fail at low level crafts. Only way i can think to explain it is like how Desynthing is calculated.
