Not Druid healers. We're about the most active people in a raid. Every raid I run, I check recount and I am either the most active, or the second most active person in the run. I can see how a healer who is just spamming the MT with the same heal over and over might get bored, but when tossing heals at 9 or 24 other people, adding in the occiasional battle rez, minding hunters pets and warlocks minions, trying to set priorities, knowing who is healing the MT, who has the OT, making sure you can jump in if they go down, managing your mana, and.... well... I don't get bored at all.

There is a reason that Raid RX, the WOW Insider column that talks about raid healing, calls it Extreme Whack A Mole. My time in a raid is spent in not letting a single spell get delayed beyond the 1.5 second GCD because heaven forbid that 700 HP that my heal would have done were a half second to late on the tank.

That said, Chain Pulling might move things along, but all it does is cause me grief. Instead of using 10 mana pots in a night I use 30, when I could have just use mana biscuts for 15 seconds had the tank taken enough time to let the mana users top off. You do NOT want me yelling OOM on a trash pull any more than you want it on a boss.

You can have the best of both worlds though. A raid leader than I've run with a few times has a few basic rules. Everyone gets all the mana biscuts that they need. Every mana user is to make the very last thing they do on any pull is top off their mana. Then the next pull is done when he sees the mana topped off on everyone. We rarely have more than 20 seconds between pulls.
