There is one very good point to a part of Silverbane's comments - suggestions are usually pointless. Any professional dev team has a laundry list of 'ideas for things they could do'. The probably have pages of discarded ideas, implementations, etc. that just didn't fit. Heck, nearly every idea we've proposed they've probably already considered at some point or another. They don't need our ideas.

And they don't need to know numbers - because their analytics and data can tell them that.

The one thing they do need, and what - if you really read deep into this thread is conveyed albeit surrounded by way too many suggestions(and yes, I'm not saying I'm innocent in this) - is how playing the game makes us feel.

Put simply:
During high end content like savage/extreme, the moment to moment experience of healing doesn't require much involvement from the healer, and this is something many of us do not find as engaging as we would like.

Feedback done.
