I just read a very helpful post Heroic Instances, progression.

"Kulzor" was kind enough to list out how he would stage a fight. Unfortunately he seems to have a hunter and a druid that I don't have lol. I would love for someone to help me with a step-by-step guide that is similar to what I've quoted below for a pally tank & 4 shaman fight sequence as I'm about to introduce my new pally into the mix.

Kissell13 - here's how I start almost every fight:

1. Stop the dpsers in back (bunched up like they were on /follow). Drop totems.
2. Cast Hunter's Mark at first mob.
3. Launch Avenger's Shield and cast Misdirection on the tank.
4. Cast Holy Shield, cast LIfebloom on tank.
5. Cast Consecration, stack Lifebloom on tank.
6. Multishot to spread out more aggro.
7. About then the mobs get to the tank, or I wait a second or two.
8. Hit Hammer of Justice on the first mob to actually reach the tank. If the group has an MCer or Fear caster, that is the primary target, and I wait for that mob instead to reach the tank to cast HoJ. Mob must be in melee or it screws up Hammer of Wrath attacks.
9. Push "start on a mob macro." This kicks off 2-3 minute specials like Bestial Wrath and Arcane Power. On the tank it casts Seal of Righteousness. On the dpsers it starts blasting, but the macro on that button won't cast an instant spell.
10. Start mashing my primary attack macro, which kicks off trinkets, pet abilities, and spell rotations for each toon.
11. When a mob has about 4k health left, I tab to the next one and start mashing the primary attack macro again. Since the shaman and the mage are usually still casting, it lets them not waste a spell, and I end up doing more dps as a team.

Note: If a second mob is an MCer, casts Fear, or Polymorph, then I use the hunter's Intimidation to stun them for two seconds as soon as I tab to that second mob on my list. (I don't interrupt killing the first mob to tab around, but will stun them when I get the first mob down.)
