Need advice: static imploding because of cheater.

[Kansene]

I cleared a duty after watching a guide can anyone tell me how my clear is suddenly more "legit" than someone who used a zoomhack just because I didn't download any plugin?

One of them gives you instructions outside the game to remember.

The other modifies your actual game and provides real-time assistance that directly affects your gameplay.

If we're going to go with the ever popular use of metaphors, the former is an instruction manual to a lego kit. The latter is someone fetching the correct pieces for you and helping you assemble the kit. The kit you agreed to assemble unassisted.

To further drive home the point:
Clearing the duty after watching a guide means you researched the duty and prepared to face what the game throws at you. You operated within the terms set by the dev team and did nothing wrong.
PvE in FFXIV is a memory game, and repetition and memorization is the intended learning method.

Clearing a duty using addons means that rather than face what the game throws at you, you make a conscious decision to avoid the challenge you are faced with, and use illegitimate tools to invalidate and bastardize it. You decided to skip parts of it and create an easy-mode version. After literally promising not to do it. That is what you agree to when you accept the terms of service.
