Since today, the menus have been glitched to where it is very challenging to interact with them while running. This also affected the bard as well. However, the bard is in much worse condition than the menu, because even if you can kindof hit the marimba or your orbs, it does not count it as a hit, even if you hit in perfect time with the notes. In combat the effect is reduced but still resides. This makes it impossible to build crescendos while running to pvp or just charging them up to be ready for a pve group ahead.
I think the new spell cast delay removal for the mage caused it. Could be something else that came with the changes that got implemented earlier today, but that’s just my theory.
