We have massed out of Athica far more times than i can remember and we had no problems. It's not hard to find a spot to port from. E.g. Athica zone in, Healer area, Athica B zone line, Athica B itself, ect. I truly don't see a reason to waste the time making another port neck quest when so many are already available. Don't forget that SNP is still around and you can obviously mass from the small dock area, the pool area, NNP monk guild area, and a few others. You don't have people running around those areas to check vendors all the time anymore so most of those areas remain virtually unused. Sk is also a great neck and it's pretty close to Thurgadin anyway so why make a neck for a city that is one zone away. It doesn't make sense. There are plenty of zones, each with their own good share of mass options, for guilds to choose from and another neck would just be very redundant.
