The Novus to Nexus upgrade I see as a much lesser problem than the atma acquisition, personally. I got my atmas during the initial rush, meaning that I had to run to get to FATES in time to participate. Now you mostly solo all the FATES because nobody's really doing them. That makes a huge difference. Farming lights will certainly take longer, but the people who haven't hit that stage yet (myself included) were never going to go all out farming lights. The only exceptions might be people who started late or are working on secondary+ zodiac weapons. I like that nearly any activity I take part in will generate some light so I can pretty much not worry about it and the upgrade will eventually come. This is how I always intended to handle that upgrade.

I see what you're saying and it's true it will take longer for people finishing today or in the future, but a lot of those people were going to be taking their time with the upgrade anyway. I would have completely wasted the opportunity to run with light farming parties since that's just not really how I enjoy playing the game.
