I vote for nerf but it's probably too late now since 4.2 is near now. One of the reasons 4.1 didn't feel like a complete package in my opinion is because shinryu ex wasn't something most of the community could strive for in a reasonable amount of time. Patch 3.1 is known as one of the worst patches ever and they repeated the same mistake by making Shinryu Ex like Thordan Ex, in my opinion. Didn't the raiders get ultimate bahamut?

To me the best times of FFXIV were when a lot of the community was actually interested in the time required to clear/farm these Extreme primals like sophia, susano, lakshmi. Everytime they add the Thordan and Zurvan like primals it really ruins what could be a fun time for most of the community. Raiders are still running omega and savage, that should be enough specially considering the ilevel on shinryu ex weapons is something raiders don't even want/need. If we study each patch one by one, you'd come to realize that the best ones had the "easier" extreme primals.
It gets your FCs involved, your linkshells, it's really the best time.
