The other day I was participating in the Barathrum Centrata event in center Imperial sewers
with a group of 3 while we met an entire zerg there doing the event.
I completed the event 8 times and only got the achievement for killing the boss and 200 telvar stones once .
Damage dealers did get reward and even a few stonefire scamps.
While I did a lot of healing to the zerg and my own group in the ongoing fights with the bosses and the enemy player,i got next to nothing as reward..
I felt like I wanted to move on,but my group wanted to stay because they got nice loot so I stayed for them.
Maybe revesion reward calculation?
And if reward calculation can't be altered,at least give healers AP for keeping alliance members alive or something.
