Now, would it make more sense to buy a lot of keys and then sell them on the Exchange to build up the EC to buy one there?
Buying 100 keys is not a guarantee I will get it, so at least in that way I could just buy it outright?
Do keys sell that well on the Exchange?
With keys having dropped so much in price, it might be a good idea to sell Fleet Ship Modules along with keys, or possibly instead of. Both sell well if you price them appropriately. Though, you miss out on the Lobi for the new Temporal set going that way if you don't the Lobi for those already.
