Am I the only one that sort of kinda likes the nerf to SoF?

[Fyce]

so now we got this big brainless playerbase that can't incorporate other ppl into their play, to clear an easy fight.

You're right, this "brainless playerbase" is big. In fact, it's so big that it has become one of the primary type of players playing MMORPGs.

This herd of idiots, as you call them, are keeping the game alive.

The least you can do is accept that they should be able to purchase Heavensward and keep paying their monstly sub so SE can make the hard content you want.

FFXIV is designed to have content appealing for as much player types as possible.
The idiots are not leaving and they will keep having content made to match their needs and expectations, just like you also do have content matching your needs.
Deal with it.
