i90 Does not make you a good player

[Amyas]

It's always been Skill > Gear - the problem is there is not much skill required in ffxiv, let alone enough to really outshine the other carbon copies of your job. You can be full i90 and not know how to play your job just on the basis of collecting myth points.

Alternatively you can say that a person who chooses to invest their myth into their main may be more skilled than say a person who could've simply gotten lucky in coil and won some drops for an alt.
