I run heroics on my alternate healers for fun, practice, and justice points. I keep getting tanks that want to skip bosses, like they are just there for the two Frost Emblems. I would go along with this during those runs. I understand that people were doing the dungeon only for the emblems. But now, it doesn't make sense to me.
I tell them, hey all the bosses give Justice Points. This is especially weird when the party is blowing the content up quick. The other day doing Old Kingdom, I got the tank to go down and do the Mushroom Boss. Three players got the Heroic Dungeon achievement even though it was obvious they had done the dungeon before. I haven't gotten a calculator out to see if the extra couple of minutes to kill Dred is worth 16 Justice Points, but I'm guessing even if you have killed him 1000 times before it's going to be worth it.
My alternate Restoration Shaman got invited to do Sindragosa and The Lich King even though he has never been inside ICC before. I know the fights well. I kept up my earth and water shields, hit riptide on cool down, blasted out fast lesser healing waves and healing surges to low health players, and chain healed when everyone looked good. Even under geared with no experience healing raids my heals were close to 35% of the heals. I realized I never used my Mana Tide Totem. The extra Mana might have been useful to the damage classes, but I'm not sure. I'll remember it next time.
We had two restoration druids. One of them was blowing up the meters (45%) with rejuvenation, regrowth, wild growth. He didn't cast a single Nourish or Healing Touch (not even with a Nature's Swiftness), but had both of them talented in his tree. On my Alternate Restoration Druid, I decided to not take any talents buffing those spells, specifically Naturalist and Empowered Touch. Instead I put the points in the Blessing of the Grove, and Nature's Majesty to buff rejuvenation and Critical heal chance.
The other druid barely used Wild Growth and as a result was very low on the meters. I think he must have been concentrating on tanks. We could have easily replaced him with a damage player.
I was pugging with a bunch of people I don't know, so I kept my mouth shut and just enjoyed the ride to Kingslayer.
