The developers stated over and over that the reason they are dumping down jobs complexity is because of the average player performance.

FFXIV player base lack information. The majority of them don't know where they stand in terms of performance. They assume they are doing OK, but are they really?

I personally know a lot of players who were shocked to hear the truth about their performance. Mostly told by a friend or an FC mate. These players did not quit the game (Which for some reason a lot of players assume is what's going to happen) instead, they got better.

Giving information made a difference. I'd assume because the information came from someone they knew instead of a complete stranger.

Now if the game somehow made getting this information accessible without the need to refer to a friend or an FC mate. Things could change for the better.

And just to be clear, I don't think OP is asking for top performance. They're asking for basics. Which yes, the majority of the players lack.

I'm beginning to assume that people got used to seeing bad performance more often that they took it as the norm. Which is part of the problem.
