People work really hard to level those classes up and get the class sets, which are always so nicely designed, and then we can't do anything with them except craft or gather. A big draw of the glamour system is styling on your enemies in battle, but these fantastic sets can only style on the trees you're felling and the potions you're mixing. It's sad. I can see the logic in keeping the war and magic class sets job-locked, but most players spend more time battling than they do gathering or crafting.
So many times i have seen a nice shirt or a hat and gone, OH THAT WOULD BE PERFECT FOR MY BARD, or summoner, or white magic, only to find out that it's only for alchemist or whatever and even if i levelled that class and got the set, i could never do anything with it except make more potions.
If class sets for hand/land could be glamoured onto whatever we liked, it would encourage a lot of people who otherwise don't care, to pick up the crafting and gathering classes.
Maybe you guys could open them up to be glamoured onto other classes? Or create identical and dyable versions set at level one with no stats that we could glamour with? I would be willing to spend money on the mog station for these very much.
