I get these every single time
- 2.5k heal
- 5k heal
- 2.5k damage single hit
- 75k dmg
- 10 kills
- 1 killing blow
I get these most of the time (generally atleast 3+ per wz)
-5k dmg
- 300k dmg
- 25 kills
- 75k healing
- 1 solo kill
- 1k defender
with sometimes
- 3k defender
So I would say I average around 10 per warzone with 8 being the lowest and 12 the highest I've gotten so far, both of which happen very rarely.
