I think, while there are some actual changes that need to be addressed such as texture opacity and lips, saying you're "mourning" a videogame is generally just indicative of an overly unhealthy attachment to an ephemeral concept in your computer. What will you do, 10 years down the line, when XIV shuts down?
Either way, there's changes to be addressed, but this thread is a crash course on how not to do it. Look at the JP masterpost of criticism. Civil, proper with proper alternatives.
Please remember, it's only a videogame. Go outside and take a deep breath. Things will be ok, just a little bit different.
