Let us select battle ost. Implement in-game voice chat, its 2024. let us lower the volume/mute music, fully customizable colorblind settings.
also probably my biggest wish, remove the gacha-type gear building system, and in fact lets just remove all the gacha-type methods of all customization. We paid full price for the game so why dont we have easy access to desired titles and banners, like at least let us purchace them with coins and keep the shell out machine as an alternative way of obtaining them.
