Sad to inform you, no "good other stuff". You sure won't be able to get 10 Mk XII items from the omega marks, Borg neural processors and little dilithium you'll get.

From 12 proto salvage, for example, you'd get less than 4 000 dilithium. For one Mk XII borg weapon under new system, you have to spend upwards of 10 000 dilithium, AFTER you actually unlock the option to buy it by participating in the rep. system...

Just find another game...
