While this might not seem of much help to you, I do suggest you try to go over the fight, try to understand his abilities, find out what seem to be the weaknesses of your raid, and analyze why you are having trouble. Depending on what the problems stem from, you can adjust your tactic to that.
Example:
You mentioned that a lot of time Domo is not under control - he walks around killing people. Now, we know that this is because on teleports Domo loses all aggro on everyone around him. Usually, you would want tanks to pick him right back up, but the issue here is that Domo is fast (so slight lag will make him go out of range of taunt) and that it gets resisted often. Placing another tank might solve second part, but it still does not address the first.
So, what you can do is get a class that can quickly and reliably pull Domo back to tanks, while being able to take some damage. We prefer to use a Hunter with distracting shot - they have the range, the +hit items to ensure the hit, and it generates enough aggro so that a heal or two from the core of the raid won't be enough to overcome the aggro. And with mail, they can take a hit or two before tank pulls it off.
Example:
One thing, as someone already mentioned, the shields can be either Damage Shields or Magic Reflect shields. While you don't know which one is next, you do know when it will happen, so if you poly right before the shield, mages should have little trouble keeping the Healers sheeped.
Mages can miss the poly on healers sometimes. Sure, it can happen, even with the 5 second warning - the sheep can get resisted or the mage might miss the timer. While it shouldn't happen, you can still ensure that it won't happen again.
I) Curse of Shadows can help to eliminate resists.
II) The warrior that was tanking first mob that was killed can switch to "sheep-guarding" duty - just stand there, and if a sheep does break loose, he can taunt it (without attacking) and keep it on him for a few second necessary to resheep.
Third Example:
The kill order does make a difference, but one has to recognize what the difference is. 1 elite - 4 healers - 3 elites order is easiest to understand and execute, but can put a lot of strain on your healers, and does require quite a few tanks.
2 Elites - Healers - etc often requires quite a bit of coordination from the raid (burning multiple elites down to low % and keeping them alive), and can get a bit messy, but it requires less healing then above
Last one - 3 Elites - 1 Elite to 15% - kill 1 Healer - finish 1 Elite - 3 healers - is easiest on your healing, because at one point you are only tanking 1 elite, which can give you time to regroup and res and regain mana. It is my favorite method, but it does require the tanks to be on the ball at the end and pick up the 3 healers.
Of course, what works for you is for you to decide.
So in the future, you might find that you cannot rely on a lot of strategies posted on the board - because your raid's strengths and weaknesses are different - so you have to tailor your strategy for your particular raid (and by you, you mean whoever is planning your raids). Also, a lot of small things get omitted in those strategies, because the encounters become so complex, so you have to find out those on your own. Identify the weak spots in your system, look for what can be done to prevent them or at least provide extra security.
