Again, based on data there are 189215 individual logs for healers. Of which 63207 are Holy Paladins, that is a 33.4%. So we should expect Holy Paladins to be around that number when you look at healing output. But they are often two or three times as many. Additionally, if they did not have that overpowered healing output, they would not be overrepresented even on stacked situations. And finally, data shows that their max healing score is 148.89 compared to the second healer who is the druid at 125.19.
I’m not going to look at 1000 people per boss. I can give you 300. The picture changes little. Holy Paladins remain overrepresented.
