As I have barely crafted and know very little about the profession besides the fact that i blame EP4's for the immense drop in mining MU, I can't say if any new BP's would help or not. Logically help if they need more mined/looted materials instead of nanocubes?
No and no. What you do need is healthy demand. An example of healthy demand, or virtuous circle if you want, is the materials used in enhancers, like pyrite used in damage enhancers which are consumed with a meaning (mostly in events, but out of them too). A very good aspect of this is that crafting enhancers is a tt sink, because the output has guaranteed less tt.
And the base of healthy demand is to have top of the food chain L/consumable, which in itself to have a meaning in usage. Again, enhancers are an excellent example and this is the direction MA should take.
Regarding MUs, depends what period you compare with.
2005: Molisk teeth and foul bones used to be 3-700% and certain woods even 1000%+. That was because gambling was done back then on tailoring and crafting furniture, which itself didn't had any meaning. But we had no L, no SIB, no need for residue etc. Nowadays EP is the biggest provider of residue, how would mining amps and ArMatrix be priced, with residue at, say, 110%?
2006: lots of ores exploded in price with the introduction of amps and some new components. But some amps were 140% or more and they stayed so for years. Mining amp % is the most sensible to economical meaning. As soon as is not rentable, miners will drop them. Currently crafting amps is a loss, the only aim is either gambling either trying to loot high amps clicks, but those in themselves don't have a meaning. There makes limited sense to use lvl13, the actual ingame reason is to hear hof trumpets. Which is stupid, as an economical paradigm.
2008: vechicles were introduced, so belkar and many others exploded in price, but vechicles have this extraordinary fundamental flaw that they're virtually UL. This was a huge mistake. They should have, like enhancers, low tt output and deterioration per usage. Something bearable, but not to keep a quad for years if you're careful with it. I think nobody would seriously mind, if the game would otherwise be ofertant, to change a quad each 3 months.
Much closer to us, ignisium exploded when ArMatrix was introduced. Right now is in a decent point, but ArMatrix itself doesn't have much meaning. Yea you have close to 70 efficiency, but as long as UL is always a better option, will not grow. Give hunters a reason to pay 150-200% on L weapons, a reason which to not be gambling, and then things will be better. But give a reason, don't force.
For nanocubes, what should I say? Crafters are also humans, you know. With IRL bank accounts, with nerves and a desire for fun, satisfaction and meaning. What nanocubes actually do, is that they dilute the input MU such as a turnover of tens of thousands of peds to not be excruciating for the crafter.
What I would like to see, is crafting to be revamped and condition slider to be removed. The only reason for that is gambling and the system must acomodate for that and is bad.
MindArk should aim to make Entropia the first-person competitor of Eve. The problem is that they begun by aiming to be a competitor for pokerstars.
