Hope you get well soon. I too recently have been diagnosed with a worsening Ankylosing Spondylitis and Essential Tremors on my hands that makes gaming not what it used to be. And FFXIV having a more relaxed and social feature to its game is a big plus for me.

Like you the challenge of mythic dungeons and raids in WoW is indeed satisfying but can be hard now. I am lucky to be in a bit of a chill group of raiders at the moment hence can raid a bit but I am more of a back up and I do not mind it
