Ergoth kills don't seem to count unless you are in the party that white's the boss. I went in with my guild and we had just over 1 party. I did attack but I was not in the party with the person who whited so I did not get kill credit. Everyone else in the other party confirmed that they did get kill credit. A quest like GPQ encourages cooperation and usually has multiple parties. It seems wrong to only reward one party with the Ergoth kill. I think the kill credit should work like Manon when doing HT-prequests where just being in the map should be enough for the credit.
