Instance: Naxx 25, Thaddius
Box: Four elemental shamans
Gear level: 2t7 1-2(depending on the shaman)7.5, one blue trinket and helm.
Difficulty: hard, takes a good group
Guide: Ok first off, I'm assuming you know the basics of the fight. So this is the worst fight in 25(and in 10 for me) naxx, everything else is VERY simple, most people should be able to do it if they are dps boxing or dps/heal boxing.

Charges: I set up auto run buttons for my shamans who would be running charges during the fight. If you can afford not to do charges, it's easy but doing one or two isn't a big deal. So I mapped auto run buttons to my keypad so when a charge hits I check my buffs and just tap auto ru. Bing! and your clone goes running and you just wrangle them around with your mouse. Try only pulling on in at a time, not all trying to do the charges on the first shift, wait two or three to pull in a clone.

Jumping: So jumping is a problem for allot of people. Find your self an unholy DK pal or buy some swiftness potions it'll take some stress off. While fighting one of the adds I take the time to set each of my shamans on the edge so all they have to do is turn, and jump. It cuts down on time and you can blame the other dps on your side for being awful if your raid gets mad :P

Places to stand: I kept all of my shamans in on the fight although I found it to be hard to do all four with charges AND hit the dps needed. Lucky for me I could hit the dps needed with out charges. So I had two of my shamans sit a little back and nuke. One sat on the edge of the add platform, you just creep, and cast away, no one will hit you. The other one I kept closer to the raid in case some one died so I could take there place doing charges. Just about where you land from jumping does the trick fine! Helps with not having to think to much when setting up for the first charges.

Well for me, doing 3 charges was my max, four and I barely dpsed above a tank, and gave me a nasty migraine to boot. But it wasn't too hard on my raid to have all four of me in there, plus I'm a blessing on Lothab and Sap : ) chain heal explode ftw!

I'd tos my 10 man strat up here too, although it hasn't been working as well... still need this guy down to go clear 10 Q.Q
