Hi i do quite a bit of crafting got carpenter to lvl 44 and armorer to 43 with a few others in the mid 30's, and from what i can see the current system actully goes out of its way to aid RMT/gil sellers.

how you might ask the answer like a lot of people doing crafting will tell you is shards.

I go can go through over 2000 shards in a day crafting (yes i am that sad) and most the time i just cant justify spending hours upon hours mining shards for what 40 exp per node so i like many others buy them off the market yes some are going to be from honest players but also a lot of them will be from bot's/RMT. shards only require lvl 1 to mine and you use a ton of them at high lvl crafting

there is a simple solution use shards for crafting for items lvl 1-25 crystals 26-45 and clusters 45+
