Question: what events count towards Dragonfall vendor unlock

[Knighthonor.4061]

some events dont seem to add to my achievement, so whats the events that count?

The ones around each of the three zones during the build up to the final battle count. If I recall it doesn't count the ones toward the end of the meta during The Battle of Dragonfall when attacking Kralkatorrik. I think that is because during that players are in the middle of the map and not in a specific zone. I don't remember if it counts the bonus bosses after the meta either. I could be mistaken though as I wasn't paying that much attention. Also for the escorts I think you have to do at least 50% of it to count. So you can't tag an escort for a few hits and then jump to a different event.

 

IMO the best way to get them is check LFG at the beginning of the meta, find a squad in the zone you need and chase the events.
