I have a feeling, that it really doesn't worth to craft low level armors and weapons. It's kinda disappointing, because a lot of us love to craft, but right now the only thing what make sense is destructing items, researching and collecting materials. Why? Well:
1. The only thing what we can actually craft are white items, because to make a whole green set is hard (for this you need a LOT of refining materials) and it gets outdated in 4-5 levels.
2. It's too hard to find the refining materials and you need too much of them. I would make it less rare and decrease the required amount for low lvl items. (for example for a lvl10 green armour you just need 2, for lvl30 3 and so on.)
3. The XP for crafting is ridiculously low, for destructing items you get much-much more.
Please change something about it! Make it more worth and give us the feeling that it's not completely useless...
