It's official Parsers are illegal in FFXIV

[ItzKris]

I can do math and watch HP bars, buffs, and Enmity meters in game. I can already observe when mechanics outpace healing, or DPS. I can time and count in my head the gaps between abilities.

Your brain is a "parser" that should doing all those things (if you're actually playing).

A parser doesn't conduct actions for you; it just presents you with more easily interpreted data.
