I have a proposal that I hope you will find satisfactory.
There are so many missions that can be done for dilithium, and as it stands, you cannot trade dilithium, as it would probably bring a major imbalance to the Dil Exchange. So, I thought long and hard about an alternative method that would allow a character to have more dilithium from another character on his/her account, without affecting the DE.
That solution is "Imported Dilithium" (if you can think of a better name, go ahead with it)
The way it works would be like this:
Below the spot in the assets window for dilithium would be a spot for dilithium you have received in a trade from either another player, or mailed to yourself from another character on your account. This "Imported Dilithium" would have the following restriction placed on it:
-You cannot use "ImpDil" on the Dil Exchange.
What it can be used for is:
-buying alternate ships from the shipyard for Dil
-buying weapons, Armor, Consoles, etc from vendors that use Dil
The reason I am suggesting this addition is that there are surely people like myself who cannot spend alot of time farming Dilithium to replace a ship or get some gear.
I hope this suggestion is looked at by devs, and I hope my fellow players will like it too.
Another possibility might be to have Dilithium tradeable only as Ore, so the person receiving it would still have to refine it (and be subject to the 8k/day cap). This would keep any one character from loading up too heavily on Dilithium from other characters.
