this is an interesting idea for some of you developers. ive been playing for a couple of months now and after doing dozens upon dozens of stf's ive aquired a few tidbits of neet stuff, i have about 5 borg sets with assimilated modules, one full class 10 omega set, but no full maco set. i have plenty of maco shields, deflectors, all class 10, 11 even a couple of class 12's. but i have had NO impulse drives. infact i dont know if anyone else has noticed but ive hit a dry spell of just getting one chip, even after completeing the optionals.
this is my idea and ive seen it in other games and its quite neet. Make an exchange system. you have plenty of NPC's sitting around that are just not usefull at all. so make one of them an exchange officer or stick a shifty ferengi trader in there that will trade your maco, omega or honorguard gear for a similar set item of only the same level and type. for example, if you have a lvl 11 maco impulse drive, exchange it for the omega one, if you needed an honor guard shield and all you had was an old omega one that you were using a while ago but just couldnt bring yourself to sell, trade it to the exchange officer! get the part you need.
Something else I'd like to see if they ever let us go to Ferenginar is a black market. Where we can sell our bound goods, but there is a risk. Depending on what the item is and worth you have a risk of it being confiscated and being fined EC or Dilth if you are caught. And you lose the item.
