Please help - New to tanking with DPS

[Toned]

I currently run Prot Pally, resto sham, 3 ele shams. I am in the process in between my guild raids/2v2ing of replacing my pally for a DK. Once the DK is able to hold agro off my shamans I'll switch to 4 ele + DK. Here is what I would suggest doing you have a couple options on your key layout.

Option1: Convert your tank rotation into a single macro that you can mash, then bind a shaman dps rotation to that same button.
Then possibly have a second key that has your dk dps rotation and then your shamans with some dpsing others healing. - Down Fall to this Method = If your DK misses a spell you have to wait untill the macro cycles back through, or manually click the spell. -- I use this method currently for the paladin because they are lol easy to tank with.

Button 2 = Tank / Dps Button 5 = Tank /DPS +Heal If you run a Dedicated Healer 2= Riptide and 5 = all the ele shams just dps and the resto sham heals whoever has threat.
Rotation would be like this: 2,2,2,2,2,2,2,2,2 then tank is taking damage 5,5,5,2,2,2,2,2,2,2,5,5,5,2,2,2,2 etc...

Option2: Using your purple rotation and bindings you listed of like 3-8 or whatever you press. Keep your DK keys as is and then bind your shaman dps rotation macro for 3-8 or whatever you press when tanking. Then use your F1=F5 keys for healing your group ( pretty standard setup all shamans have /cast [target=whoever] lesser healing wave) Upside is you are in control of you dk rotation = more threat, down side = You have a lot of key space taken up on the shamans.

Rotation would be like 3,4,5,6,7,8 whatever else you do then hitting your heal keys accordingly. I usually recommend having F1-F5 bound for healing your group regardless of which setup you use, but then always having a heal whoever has agro button. That you can mash while dpsing /cast [target=focustargettarget] or /cast [TankName-targettarget] or /cast [Target=Targettarget] if you are keeping the mob targeted on the shamans.

Option3: Convert your tank rotation into a single macro that you mash, and then overlay it with your shaman spells. This way you are doing a manual dps rotation on your shamans while the tank is mindlessly mashing your purple tank rotation.
Example:
Shaman Keys
1 = Chain Lightning, 2 = Lightning Bolt, 3 = Lava Burst, 5= All Heal Tank-Targettarget or FocusTargetTarget (should always be the heal the tank button if you are keeping agro) 6 = Wind/Earth Shock, 9= Flame shock
DK Tank Macro bound to 1,2,3,5,9 and then mindfreeze bound to 6 (i'd assume you setup a round robin /castsequence macro or whatever you use to round robin #6).
Upside here = Higher shaman dps... DownSide = Tank Misses a spell your rotation is off /cry.

Rotation would be like this:
Single Mob: 9, 3, 2, 2, 2, 2 (if you have the haste otherwise only 3 lb's), 3, 9, 2, 2, 2, 2, 3 etc.. Any time Tank is taking more damage than you are comfortable with throw in a 5 or 2 5's.

See this thread: Utilizing /click to run concurrent castsequences for shaman dps rotation macros. If you want a 1 press shaman dps key.
