The Omega Rep gave 500 Marks and about 9000 dilithium because it was the amount to purchase one Mk XII ground STF piece. Romulan Rep gave 750 Marks and about 32,000 dilithium because it was the amount to purchase one Mk XII space set piece. Since Nukara Rep has 3 ground sets, then it will give about the same as the Omega Rep. So about 500 Nukara Marks and 9000 dilithium.
And the ground sets is another problem nukara reputation has.
Someone didn't think it through...
Losing your STF set fast remodulation ability AND it's not a costume?
Why the hecko would you waste your time getting 12 marks per mission just to give up both fast remodulation and the ability to wear or change costumes?
I'd actually like the EV suit, as a costume - not that I'd work on it at 12 marks for a mission.
None of it makes any sense.
Personally I won't be playing nukara on any character and I am done re-grinding, so whatever plan they had to resuscitate level grinding they can think again.
Besides, I am still waiting on fixes for the season 7 reputations where both have bugs at t5 to this day.
I am not going to risk playing through 5 tiers and find blocked items again and least of all for next to no marks.
