Guild Wars 2

No matter how many bosses I kill, i still don’t get any reward at all at the end from it.

Two possibilities:

• You aren’t doing enough damage to get credit. Easiest solution: join a party. You can also update your build or grear.
• You aren’t staying in the Blitz area — you don’t get credit if you walk up the ramps to the Gauntlet (not sure when this changed, but I found out the hard way).
