Replicate the Sigil menu scheme---get sigil and select all the buffs you want and then select done and you get it all in one shot. Always wondered why they made it so simple in the cities, but so broken at the Campaign Arbiters, where timing is more crucial.

And something REALLY needs to be done about that event skipped mess. This is a long standing issue with campaign. I understand the need to keep people from exploiting things like dropping hate when in menu and such...but there's really no reason for you not to be able to talk to an NPC (also an issue with using a conflux you already activated in abyssea). If they aren't going to take out the interruption effect for Campaign, then do something about the NPC's being in harm's way. Either move them away from the fort, or change the pathing of the bosses so they don't go straight to a spot right behind the NPC and start spamming AOE's.
