I've been hearing about all of these new features, items, etc. that are coming to Heavensward, but haven't heard anything about the dye system being changed in any way. It would be great if we could dye individual parts of the gear instead of just giving us one option to color the whole thing (while keeping some of it the default color, depending on the gear). I'd suggest something like this.
Let's say the gear is a body piece and it has white, gold, and red on it. With a new system implemented, you could separate that like so:
Color 1 [white]
Color 2 [gold]
Color 3 [red]
and simply allow the player to click which one they want to dye and BAM! They can still keep part of what they like about the default while coloring the rest or they could just color the whole thing if they want. I really hope they plan on doing something like this in the future to give us more options.
