SE just make a vanity slot to solve all your issues with this.

And there is one reason why i dont want them, i just dont wanna see Rogadyn Paladins in a Yukata tanking, sry but thats something that would destroy the flair of the game.

No, what would destroy the flair of the game would be seeing the return of the Optical Hat+Scorpion Harness/Haubergeon army.

Any player can wear whatever they want at any time -- right now (provided their jobs/classes fit the bill).

And a vanity slot system would not change that aside from giving the player an option in how they look. Gear change macros are just that, and you're attempting to present them as an alternative when it is not much of an alternative in the first place.
