I just did a mission from Mirv "Not a good reason" which required 4 Trident Blasters each at the cost of 2500. After i bought 4 of them which is equal to 10k credits i get Boar 79 at level 1 which sells at 1250 credits. I think the devs forgot about the missions in the Omega update and i hope it gets fixed soon.
I believe so as well. Remember back in delta and before that the mission item would be worth more then what you spent on the other items. Now it isn't.
