I would be very surprised if NI equipment stopped tiering (more than other planets' gear, anyway). The reason the freebies stopped dropping was not a balancing issue but because the PP has to pay MA for each of those freebies, and presumably the NI PP stopped paying MA for these items. Tiering doesn't cost the PP any money since it doesn't add TT value to the item. Hopefully MA will "unstick" tiering this year but I'm not going to hold my breath since I can imagine tiering rates are a balancing nightmare.
