Reverting the Glory nerf would leave the NecroFury build around 16k, which is about 1k higher than post-tier nerf Kyrian, Night Fae, or Arms.
Given its room for failure due to loss of uptime and its weaker multitarget capabilities though, I think that small advantage is fine, and it still may not even be the primary build (since this raid has a lot of multitarget and target swapping), however it would at least remain an option.
Going forward with the nerfs as is, Necrolord would be completely off the table, outside of buffing your favorite Warlock, which has not been reason enough for anyone to prioritize it so far throughout this entire expansion.
