tldr: I think the outfit system needs a favorite function. Seems like it would be easy to implement and would make it a lot easier / more fun to mess with outfits.
I'm loving how many motifs the anniversary event is injecting into my crafter, BUT, it doesn't help the main problem I have...which is that the outfitter UI doesn't provide a way to easily pick out or categorize styles. The grid system it uses to show all the motifs seems to require that I remember the location of whatever motifs I remember that I like or dislike. For me, it would be helpful to narrow the probability space of all the different options, whether by allowing certain styles to be grouped into a separate menu section, or just being able to highlight them. I did post about this in the outfit feedback topic in the PTS forum but am unsure if that gets looked at as its been a while since the system has been out...
Even before I had a lot of motifs, I remember just trying to sample them and see which ones I might want to buy or grind dailies for, and even then, there are so just so darn many, looking through them would just burn me out.
So, my answer would be a favorite function. Even just the ability to highlight different motifs in the menu (but hopefully more than that...would be nice to be able to make thematic groups). Maybe some enterprising addon coder can make it happen?
What do you all think?
