Starting out soon- Combat, Support and Crafting class synergies?

[Mr Killer]

Ok, I'll stop using my mats and sell them, and save the expensive stuff like hardened metal?

depends on what u want, if u plan to go engineer id save up the mats for a short heavy cade which is support level 11 crafting if u need the recipe (irrc) and also id save up cheap materials that cost less than 10k like hardened metal or crooked sticks for example and sell stuff like eagle feathers and wood of glasir on the forums here just look/post in the crafting section if u don't know the price to sell it at and/or on the auction hall (use it as a reference for selling on forum)
