I skip Unions 95% of the time. I'm usually late to the battle because the /cmap is so laggy and the messages in town are useless (unless someone can explain to me how to properly read them). I'd rather try to claim a mob or get out of the way of the incoming wave than spend another 30 seconds joining a union. I'd love for union registration to be automatic or part of the Allied Tags dialogue.

Click "Receive Allied Tags"
"Would you like to register for a Union at this time?"
None.
Adder.
Bison.
etc - Click one.
Now you receive tags and NPC buff spams.
