I think GW2 should make it so that Aetherblade events during the invasions either don’t spawn champions or those champions don’t give drops.
I have taken part in about five failed invasions and only one successful one. Based on what people (especially commanders) were doing during the events and based on reading the map chat, it was obvious that could have successfully completed the invasion event but people were more interested in farming Aetherblade events to kill the champs for loot than they were in actually achieving victory against Scarlett.
I’m really not against farming, but there’s a time and a place for it. These events are suppose to be about defending the zone from an invasion. They are not suppose to be about grinding Aetherblade captains in hopes that one of the Deluxe Boxes drops an exotic weapon.
