So as on reddit , and experiance. i’ve noticed that as a healer, blasting out heals.
You end up with being 43 out of 50 on the rating system.
It seems that the chest you get is rank rated.
As tanks and healers are the main backbone of every grouped instance / adventure the are being punished for it in invasions when it comes to reward.
i’d suggest a seperate heal output and damage recieved top 5 so they get fair rewards as well!
Ratings are stupid anyway.
Not only in invasion but also war, they dont mirror tactical efforts and planning but simply present plain numbers without context.
Eg you cant heal, if the other side doesnt deal damage.
You can deal even more damage, if the other side has strong heal.
