Thanks for all the good feedback everyone.
The only thing I would like to add on the most controversial topic of a healer dps is this...

The point I was trying to make was there is no reason for a healer to stand there and do nothing at all. I have been in dungeons where the tank or dps do not need a cure and the healer stands there doing absolutely nothing mob after mob after mob. There is no reason a healer cannot throw an aero or stone or holy out there now and then instead of absolutely nothing. Even if you have to cure maybe once, there is no reason to just stand there otherwise. You are just a body at that point and a waste of space in the pt slot if your not even drawing your weapon or casting a single spell pull after pull after pull which I have encountered again and again. Its good to learn early on so you know how to manage enmity, mp and timing.

And as for the harassment, I doubt it is considered harassment to kick someone for DOING NOTHING but following the group. I will have to check tos but if your in a dungeon and not doing a thing there is no reason to keep you imo.
