Is it possible that someday, by either HOT or a weekly update we get the option ingame to dye our weapons?
it would be a really good upgrade for immersion, maybe having some exceptions like a legendary weapon, or part of it ( sunrise blade not dyeable but cross-guard, grip and pommel could for example) to keep it lore-friendly.
Most players would benefit from this, just an aesthetic and immersive improvement, so that you could match your armor color/theme to your weapons as well (shield wielding players would benefit a lot)
