Why refusing customization is a fallacy

[Miscreant]

you could spec you BLM a Frost Mage, doing around 20 or 30% less DPS than Fire Mage, but putting more debuff. Who will care when, by being full ilvl220, you'll be doing 40% more DPS than people will do now not being full 190 ?

You can't just make up numbers for this kind of stuff, where does this 40% come from? Skill does massively outclasses gear, I see players in i170 doing less dps than good players were doing in 130 at level 50 in FCoB.

Back in 2.5, Relics Zeta were the absolute best weapons. Yet, people would still clear content without wearing one.

By that point all of the content had been cleared and nerfed with echo, no one really cared anymore.

I'm not really against customisation, it would definitely add another element to the game, but do you really think that players who can't learn a basic rotation will actually benefit from it? it will just make the gap between casuals and raiders even larger.
