I'd like to see the ability to change the motif of existing armor pieces.

I don't mind spending 200-500K AP on a single piece motif but what I do mind is that if I want to use that motif I have to go craft my armor again. Which means another 120+ high end material, plus all the tempers to get it to gold again (which is a lot of tempers). Even when maxed, it still takes eight yellow tempers to make something legendary and the gold tempers are rare and cost anywhere from 12,000-15,000 gold each. So just one new piece of armor with a new motif costs a ton of money and performance-wise it's no different. Plus with costumes, polymorphs, etc... why bother with a motif at all? Now, if I could pay X amount of gold plus the new motif material to change the look of an existing piece of armor, then I would definitely spend the AP on motifs and try out new ones all the time. As it stands, it's ~100,000 gold and 200,000-500,000 AP just to change the look of onepiece of crafted armor. It's not worth it.

As it stands, you have the AP grind to get the motif. The style material grind. The gold grind to get the tempers (or the writ grind, all praise RNG). Plus the mats themselves. All this work for slightly different looking shoulders (for example). The shoulders don't behave any differently or give any better stats, they just look slightly different.
