Variance in player skill is hurting FFXIV's itemization design.

Typical casual life that i'll never understand.

RPG = Character progression. That is the point of the game. To progress your character in terms of power and story.
This is true for all sorts of gamers, diehard raiders, raiders even crafters.

Niddhogg offers the BiS weapons for everyone that doesn't raid savage and is not interested in the rather intense grind of the Relic.

Since you asked: I am doing my 240 relic right now. No I am not one of those lunatics that does it in 2 weeks. So theoretically Niddhoggs weapons would be useful to me.

I do agree that if Nidhoggs weapons were directed at casuals, it might have made more sense to plop them into the normal version. Not sure how difficult the extreme mode is compared to Alexander Savage.
