These kinds of posts are legitimately misleading.
The demo build was months old, it was okay to mention that. The release actually fixed many of the issues the demo had, which was apparent with the chatter for the first few hours of Anthem's launch as people were positively surprised at the improvements.
Then they realized the game had quite a few other issues, which are being addressed in the patch. We even have the patch notes to see,
here. So it's fair to say "wait for this patch, it will fix your issue" if your issue is something listed in that patch.
These are almost always NOT a blind defense force stanning the game, but people talking actual sense to specific comments.
This is more apparent when you realize we KNOW what's in the day 1 patch, and it's clear it won't fix core issues people have (lack of content, variation of enemies, environment being samey, etc...), so literally no one is saying "wait for the patch" in response to those things.
So this rhetoric you and others claim is happening.... isn't happening.
The game has released in a poor state, everyone can see this. Some are enjoying it despite the flaws and have hope, others are bailing as they've had enough of this model and all the excuses.
This idea that people are deflecting all concerns saying "wait for X" is misleading and just isn't happening like you suggest it is.
