Traits, Gear and Skills profiles saving.
I would love to have such feature.
I wanted to suggest something similar since a long time. Its a tedious task to change all armors, weapons and traits every time you want to go from PvE build to WvW.
About it being a Gem Store item, I am not sure. I think such a necessary feature should be provided for free. Atleast one extra “profile” should be available for free.
I really don’t know why they got rid of the build setup from Gw1. Obviously it would need tweaking but it was a great feature. Having to sift through screenshots to find a previous build I’ve used is painful.
