I haven't tested anything with this, but it seems like this would then have the unattractive side effect of making Cartel armor much cheaper to repair, since it sells to a vendor for one credit. While I doubt this was their intention, I suspect they will have many more unhappy people around if true (to reiterate, I didn't test this).
As an aside, back in the old days of repair costs, costs were determined by percent repaired, not a flat rate per durability point. This meant that it cost the same to go from 40 to 80 durability (for light armor) as it did to go from 60 to 120 durability (for heavy) - ie, light armor wearers had to repair more often, for the same price. While I don't really raid anymore, it would be unfortunate if the increased repair costs made this an issue again.
The more I think about it the more I wonder. I do have a character with the Trailblazer headpiece, I might need to send those mods to that character and see what the costs to repair are. It's only a couple of dailies to test. It's possible that was the previous problem, those with cartel gear had inordinately low repair costs (because it was just the shell cost) and now it's much greater, which is the reason for the uproar. Personally I haven't seen significant changes in my repair costs, but I don't run Ops either.
