Has anyone confirmed that healers are, in fact, not getting credit for simply healing? Or is that simply being extrapolated from the OP?
I ask, because the mechanic of "healing = assisting/tapping" has existed for a very long time, both in and out of fellowships. That's why you'd lower somebody's XP by healing them when you weren't grouped. The presentation of open tapping spoke to healing specifically....if you healed somebody being damaged by a mob, you've effectively tapped that mob.
So, before we start saying things like "healers are screwed"....has anybody actually tested this behavior on live?
The forums are not an accurate representation of the thoughts and feelings of the whole player base. Those who like a particular feature are in the game enjoying that feature. Those who don't like it log out to mention it on the forums. It is a relevant but biased source of feedback, and any claims of community desire should take this fact into account.
