My observations re: NIN on opposing side so far is they're squishy so fun & easy to kill with my Summoner. To be fair, the NIN skill set is new while I've been running SMN for months and in the occasional random 1v1 encounter against most classes I practically always come ahead.

Observation re: NIN in my alliance- lowest score ever was when a premade decided to forgo Markets altogether and guard our OP along with 4 hidden NIN's. Seeing them stand there not doing anything each time I passed through to mid, and seeing the score distribution and point capture my I finally asked them what they were doing. Sure would have been fun for them to pull off but of little strategic value vs capping ands holding markets. Having a match doomed by a higher portion of alliance members who have priorities counterproductive to a first place win is why I resent GC-based queueing.
