Dear Blizzard,
I hope someone reads this since your support team always stresses to make posts about issues. The quest Swarm Defence in Ardenweald had my blood pumping at about 180 blood pressure, multiple times. The quest doesn’t work in multiple ways:
First off the ball very often misses even though the target was in the targeted circle and has not left the area so far as that it should miss.
Second off when the ball does hit, it very often does not count towards the quest even though the insect falls out of the sky.
Thirdly and lastly, on very rare occasions I hit two with the ball and they fall out of the sky but only one is counted.
I finished the quest because it had a conduit attached to it I needed, but please please please fix or/and fine tune it because its enraging to complete.
