Reffering to this issue i posted earlier today: #4800
new idea
Could the Destination Role be added in Player/Unit info > Condition trigger?
I think it is a better idea if the other one would mess with combat log trigger.
Second idea would be adding the Destination Class option in the Condition trigger, this could sound useless but to me it would be really helpful while making weakauras that check for specific class/role being in the party
