I've avoided healing for 9 years. Literally until this year I had not touched a healing class and so i never felt comfortable contributing to healing discussions beyond the expectations from a tank/DPS position. ..
I don't know where you guys are getting all this standing around time. People just EAT stuff all day. I can top people off and shield them all day and still BLAMBLAMBLAM from full to dead. Like every roulette.
I'm guessing this is different in hardcore raider/instance running.. but.. yeah. Your average instance in this game has plenty of healing to do. Maybe not standing around NEVER pushing your dot or your damage.. but.. still. LOTS.
