Why can't I blacklist someone while in Diadem?

[Destati]

They really need to make it possible to blacklist people while in duties. Yes, you could simply leave the Diadem and reenter in hopes of getting a different instance but 1) it doesn't always work, and 2) in other duties you'll have to eat the DF penalty if you leave when vote-kicking doesn't work out. I've never really needed to BL a lot of people outside of bots during the time I've played this game, but almost every phase of this restoration I've come across people having the same discussion about "traps".

This alone should add the bot you just reported for RMT to a temp block list that clears when you log out.
