You're only interpreting that way because you personally want change. When that's not what they're saying.
When they say necessary change they mean things like if there is a issue with the character model, they will change the character model to fix the issue.
For example, when they adjusted the moon miqo'te fangs, they had to adjust one of the miqo'te mouth to fix the clipping of the new fangs.
That is what they mean by necessary adjustments.
Not "we're going to change the characters because people are complaining about a barely noticable extended eyelash or slightly bigger lips"
And to extend off dynn post, changing characters leads to more bugs and texture issues this on top of more and more complaining arising because I don't know if you notice but everybody wants different adjustments.
There are people that like certain parts of the update and there are people that don't like anything and there are people that like everything.
SE can't please everyone. It's extremely unrealistic to expect them to keep adjusting characters onward in 7.x.
1.1 is what we're getting. They already have a ton of bugs to address, they're not going to add more by changing the characters.
Again, they're not going to do huge changes to characters for the live game where people can actually play the game.
This sets a precedent that SE can mess with our characters anytime they feel like.
This sets a huge unease that our characters are never safe.
They would also have to show us what they changed everytime and also give everybody a free fantasia and SE is a business, they're not going to do that.
My friend told me wow players went through the same thing they got over it in time, you all will too.
Instead asking thing to be reverted, ask for more character customization in the future.
That's the better option than upsetting players over and over by messing with people's characters.
The only time it's acceptable to adjust characters is when they do graphics updated just like what they did for 1.0 to 2.0.
With a game as big as FFXIV theyre not going to just causally change people's characters after the game is now live.
We have 10 days until early access, best you can do is make peace now and either make a new character or try to get use to your new look.
