1. Let's practice full disclosure and mention that most of the "whine" regarding healer DPS comes from players who are either adamant about not improving their reactive and/or lazy playstyle or are refusing to consider and apply the tips and general information liberally provided to them.

2. Field DPS as WHM or as SCH is fine even at lower levels provided you use cleric stance. What time you lose by not having the output of a true DPS class you gain by being basically indefatigable. Then, at 45, WHM becomes a faceroll trash compactor with Holy.
