Things like ^this^ are a waste of the 2nd dye slot.
There are many items where dye slot 1 changes multiple areas to different shades of the same colour.
When dye slot 2 was added in patch 7.0, these 1st dye slots on these items were not split, meaning that in many cases the only remaining areas which could be assigned to dye slot 2 were small and pointless - such as the tiny circles in the image above, or a button on a jacket. Quite disappointing.
I assume the reason for this was that the developers didn't want to disrupt any existing player outfits made before 7.0. If that's truly the reason, I disagree with it - but there's an easy workaround that would avoid the issue nonetheless; a priority system.
What do I mean by that? Let's use the body item pictured above as an example. With a priority system:
- Dye slot 1 would behave the same as it does currently. The metal and fabric are both dyed red.
- Dye slot 2 could include certain areas that are also assigned to slot 1, but it would be given a higher priority. When a dye is added to slot 2, it would overwrite those areas which overlap with slot 1.
Currently:
Dye Slot 1: Metal + Fabric
Dye Slot 2: Tiny circle details, I guess
With priority system:
Dye Slot 1: Metal + Fabric
Dye Slot 2: Fabric (Overwrites the fabric colour from slot 1)
In the latter case, the metal on the arms would be red and the fabric on the torso would be green. Outfits created by players before 7.0 would remain unchanged, and the allocation of dye slots would make much more sense. Problem solved!
This solution should be very easy to implement, and I'm surprised it wasn't designed this way from the start. I doubt the developers will read this, but please consider adding this feature and redoing the 2nd dye slots for older items to work this way.
