Please have someone fix the Counterattack! quest. There are so many bugs involved here I don't know where to start.
1 - Line of sight issues. It's an open area and you have to be practically standing on a mob or you'll get line of sight errors.
2 - There is only one drop per boss kill (banner). Grouping is meaningless when anyone can run up and loot the item and run off. Currently, there is a level 16 (why are they doing a 20+ quest?) camping the area and attempting to gank the item at every boss kill.
Suggestion: Please make the banner lootable by everyone that did damage to the boss. It's insane that a quest item off an elite kill can be ganked by someone that just stood in the back behind the defenders and ran in to retrieve the banner.
