Symphony of the Void and Chorus of Night are essentially the same rune, but Symphony works on spells and Chorus works for combat arts. For the new runes on the Panda this year Chorus will be available in either red or blue, but Symphony is only being offered in blue. This puts a big limit on casters since the red can be put in any of 16 gear slots, but blues are limited to only 3 options. Please give us the option to purchase Symphony in either red or blue!
This is already in https://forums.daybreakgames.com/eq2/index.php?threads/panda-2021-runes.600903/ its one of a number of issues with the new runes.
I see the other thread, but it still hasn't been addressed. Caith said the stats of Symphony being less than Chorus isn't a bug, but still hasn't said anything about the fact that casters don't have a red version available, while melee can choose either red or blue. We only have 3 blue slots total, so it severely impacts choices for casters.
We appreciate the feedback on the runes, but this is not a bug as is. We won't be changing the runes this year, but we will consider it for future updates.
