As I wrote: I don't play the game as a race. I play it for fun. And playing with a stop watch in my hand to make sure that the pull the next pull happens 10.1s after the last combat ended is no fun for me.

Chain pullings major advantage to me is to keep people awake. Trash can get very monotonous and boring, especially for healers.

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.

Chain-pulling keeps peopel engaged. As others have noted, any time that you paused for longer than a few seconds is another opportunity for someone to stand up, announce an AFK, and put the game on hold (if it's a potentially significant person, such as a tank or integral CC).

The goal is to avoid as much down time as possible. The waiting game is tedious and annoying. I can't tell you how often I've sat there between pulls, twiddling my fingers, wondering why the hell we're waiting and not doing what I came there to do: down bosses and have fun.

Furthermore, I enjoy the challenge of chain-puilling. I currently raid as both a Beast Mastery hunter and healing hybrid priest and I enjoy having to have traps ready (if we're down CC that night) before the main tank pulls or having to practice being a mana efficient healer to manage the quick pulls. It's fun. It keeps the raid on its toes and it makes for more valuable time that could be better spent on boss attempts and hopefully a raid first! I raid for those moments, not sitting on the sidelines and wondering why we haven't done a pull in the last two minutes.

Also, waiting until all mana bars are full? Most trash pulls pre-Black Temple don't require that much preparation in my experience. I hesitate to mention it, but if you're running out of mana during trash pulls there may be an issue there. Either some of your healers are not playing a mana efficient game (which does happen; Flash Healing priests during trash fights are my bane as a healing leader) or you're shouldering more of the burden that you should. One single healer isn't usually going to make much of a difference in most trash fights. Having full mana bars are a luxery but not a requirement. As a druid, you probably have a significant amount of Spirit on your gear and have a OO5SR mana regen; take fifteen seconds or so to regen some of that valuable mana.

Though I readily admit there are pulls where you want everyone thinking and ready.
