@Shiyo The popular opinion I've seen doesn't say that at all. As someone who is a tank main, tanking is the best it has ever been. Compare ShB to Stormblood tanking and it is immensely better.
If the game was getting worse each expansion, why is it that the game is doing so much better with each expansion, why Shadowbringers is considered to be on par with the best of the series, up there with FFVI and FFVII.
All of the arguments you have put out, I've seen the opposite of the popular opinion. Especially the story, FFXIV is praised to hell and back for its story. Even the ARR experience, the low point of FFXIV, is no where near as bad as MMO's back in the hey day. You at least level up to 50 rather quickly.
If the game was as bad as you are saying, it would not be seeing so much success. The game's massive success is a counterpoint to your argument of how bad it is. Not only that, you are basically sending the message that a game can see success even if it is shit by saying FFXIV is as bad as you say it is. FFXIV is currently the top MMO on the market; by saying it basically didn't try to get there, you don't really give a good message to other game devs.
However, popular opinion, from all the streamers, WoW refugees, new players, etc. I don't see all the negativity you say exists in FFXIV. I highly doubt the game be in its current position if it is as bad as you say it is.
Furthermore, regardless of what you think about FFXIV and Yoshi P, you cannot refute how Yoshi P's presentation and the principles he stated in it should be followed by MMO's universally.
Are you really going to say that those principles stated in that picture should not be followed?
