no idea so pissy healer I do guess

Also, I think I understand the point. It seems silly for people in the ‘healer’ role to be advocating for more involved dps abilities when the whole point of the role is traditionally understood as ‘healing/support/buff/debuff/whatever’ as opposed to direct damage.

Someone's definition of healer or support also depends on their "gaming background".
If you previously played healer in WoW then you expect them to be HP batteries that make the green bar go up constantly.
Try telling someone who played a DnD Cleric that their only purpose is to make HP bars go up though and they'll laugh in your face.
