Yes, that works. But not all of our raid members are using Grid and solution with raid warning clearly stating the name of person that is currently holding the tainted core would be gr8, if anyone knows how to implement this (same thing that DBM has).
Is there any way to implement an option which will do raid warnings with info who is the current holder of the tainted core on Vashj? BigWigs warns who looted the core but not the current holder when core is passed to another player.
I have to switch to DBM when on Vashj fight because of that option. People sometimes use macro for passing the core when they aren't in range or line of sight to the person that they are targeting so DBM warns which player successfully caught the core (if that player actually caught it) so the core doesn't get lost until the new one is looted.
