Healtagging needs a few tweaks not healer class genocide. IMO this was the answer to the problem when there were no healers so healers get also some credit. Currently it is too much but reverting back to that problem seems to whack a mole with 2 holes.
the healer must do 2% damage to get credit? what about other classes. They should fall also under the same rule then. everyone needs to make at least 2% damage. Why Hunter who presses one button should get more credit?
