Guild Wars 2

Hey anet i was wondering what can you do to fix these deminished or miss tag loot cause i been attacking mobs in zergs and it only give me a junk peice not the exotic boxes like champions for example it doesnt drop the full loot when your in a big zerg other been have the same problems please help.

You dont do enough damage to the champ. If you join a party, the damage of your whole party will be distributed to you and you should qualify for champ bags.

Be aware though, that some champs dont drop lootbags.
