Well, there are a lot of crafting refining ideas vented here and I must admit I'm not long enough playing with the current system to give an useful opinion on all those suggestions. What I do think however is that to get the crafting system into something to be used on a more primary basis there should be a long and hard look at the pricing of all blocks in the shops. I have the distinct feeling that at the moment crafting isn't very beneficial.
Take as example for instance the pricing of shards and ores and then look at the corresponding capsules. With raw materials between 20 and 60 credits and all capsules at 2 credits there's no reason to even refine the stuff. Although I hardly have seen all the crafting recipes I have the feeling the same can be said about the pricing of blocks, some seem quite cheap compared to the complex crafting recipe and number of items required, while simple ones can have a quite high price set.
I feel it should be a combination of the two, the shop pricing and the complexity of the crafting, but I have the feeling there's too much focus on the crafting part here and too little on the economics of the results of the crafted items, or in other words, the current shop prices.
As for the crafting itself, I actually do like how that's implemented. I don't find it too complex, after all we're not baking bread like in Minecraft, it's supposed to be rocket science isn't it. :D
