I've had good luck with the pugs so far. Solo, the dungeons queues pop fast for us healers. I try to make sure I have clean bags, water, and stay repaired. Maybe a mana pot, but can't remember the last time I used one (on my priest) in a heroic. Most fights I'm fully regen'd by the times it's over. I don't think I'd burn a flask, but everyone's mileage varies.

I have had my share of unfocused DPS, but nothing major. A tank deciding to tap a mine instead of picking up the mobs that the sham's totems pulled..yeah been there :-)

Been pretty much running one or two randoms a day on my priest healing to make sure I at least get my frost emblems and a few triumph for orbs. Then switching over to my warrior or druid. For the most part healing on my priest has been somewhat boring in most groups, but that means for some fast badges. On my druid things get a little more exciting, some because healing on him is fairly new to me, and some because the gear is not quite up there. I have done heroic FOS and POS with no real problems, but kinda scared to take him in HOR just yet.
