Because a rule isn't strong enough. I propose a Law that forbids SE Dev team from producing a full expac of Robes and robe armor especially for the following jobs Whitemage, Redmage, Bluemage, Blackmage, Astrologian, Scholar, Ranger(refuse to call it bard), and Machinist. My reasoning is sound, SE gave us an Expac devoted to arid wastelands and Asia in which we run around dressed in neck to ankle drapes whose only design difference is the colorful Christmas ornaments hanging from it or lack thereof.
The law i propose states that SE may release 1 Robe armor set for any of the above listed jobs but for every Robe added must design and release 3 Glamour sets that are of unique style but are not robes, and 2 alternative design armors that are also not Robes or in any shape or form even related to a robe for each job which the Robe set is intended. SE will also make efforts with every patch through Shadowbringers to remove 50 redundant and uninteresting Robe Styles from within the existing game until a 1 in 5 ratio is achieved. After which they may release more robe designs but not in excess of 2 in 5 for the affected jobs. SE will also discontinue using the style for any other jobs instead allowing it to die in fire where it belongs.
Thus proposed, we are not in the dark ages, we are not catholic nuns, we are adventurers in a fantasy world in which most everyone glamours all the existing robe sets into underwear, or swimwear. To insist we dress in such a puritan fashion except in Rare occurrences is an abomination. That is all, if this is a good idea chime in lets elevate this to Yoshi hopefully he will have it tattoo'd upon the foreheads of the entire Design team and it become his new Lifes mantra. Second only to "Look Forward to this."
