carrying unskilled healers..

[TouchandFeel]

This is a little bit weird. You would rather a healer let the tank get really low and then do Cure 2 instead of keeping the tank's HP topped up with Cure 1, Stoneskin and Regen? My Mind is so strong on my WHM that my Cure 1 always heals over 1000 HP, and with the soldiery left side favouring SCH I have to keep an eye on my MP.

Everything else in your post is good, but this one is just weird.

I agree with you as to what a healer should be doing as a priority and I may not have been clear enough with my description.

What I meant was the healer that doesn't do any of the things that you mentioned but just throws out the occasional heal and barely keeps the tank alive, and just sits there most of the time.
If a healer is able to do all of their duties, like the stuff you brought up and they still have some free time and mp then they can help DPS some. For example I personally like to toss out some insta-cast DoT's if I have a gap in needing to heal.
