People are blinded by their own selfishness. If they remove the cap from myth, it would cause an imbalance and alienate people. If you notice, as more people got relics the requirements for certain dungeons and fights became relic. People shout relic for AK/WP/Prime farming and then slowly more shouts become relic +1. If they remove cap, people who play all day would be able to get all myth gear on new jobs before they even have a relic. Then titan shouts would start asking for mostly myth gear people. Coil would shift from ilvl 70/DL to mostly myth. Logically speaking the caps make sense, but can't reason with people who are only concern with how it affects them.
