Correct me if I am wrong, but I would argue that parsing is slightly irrelevant for FFXIV. Skill expression through parsing represents more your ability of capitalize the damage windows of the dance fights than an actual skull expression over your class.
I shouldn't be parsing purples in a class that I never touched just because I read a 2min guide in The Balance. But this is common, and no, I do not consider this a player skill expression. It's just understanding of the fights itself.
Sure, for progression it is important to know who is lacking since the DPS timers are obnoxious with their enrage, but the parse tool serves less as a learning tool and competitive tool on this scenario. It is a tool to find the weaker link and prune it, simple as, and precisely why it's not seen well.
