We simply use ktm. If any mage is getting high, we stop critting or switch to frost for a few seconds. If it is getting really close we have a macro that spams our magechannel.

Shouting like mad on TS usually solves this too. Really shouldn't be a problem.

Why Frostbolt? If I'm threat-capped in the first place, the last thing I want to be doing is dealing less threat-efficient damage in the first place.

Also, it's not very hard to drop an Ignite at all (think of how much effort it takes to keep one going)--everyone just has to not hit the mob with Fire for 2 seconds.

I use a debuff filter mod, keep the filtered debuffs (one of them is ignite) near burn which is right above ktm if i see a 5 stack ignite up there a while i check to see who the ignite owner is and where they are on ktm, if theyre getting to close to the MT ill yell at them on vent and all mages in general to let the ignite roll off, normally there are other people that are watching ktm a little closer too and just yell at anyone in general that is getting too close to the MT.

When we got 5 mages in the raid for thaddius, ignites are not that big a problem. More than that, and it can get dangerous.

We usually start out slow with Arcane Missiles until 2nd or 3rd phase shift. Have mages install ignice addon, which shows how much ignites are ticking. Have everyone have a "KILL THE IGNITE" macro that announces in their mage channel. At around 50%, they shouldnt have much aggro trouble anymore, until then, they just need to watch the ignites a bit.

you just gotta watch the dmg meter and when one person shoots away for too long say "fire mages stop" and 2s later the ignite is gone and the mage is saved... hell everyone could just stop their current cast and start casting a fireball and by the time it would hit thaddius the current ignite would have dropped

The mage was right, we've also seen Ignites ticking for 31K or higher. What makes Ignites get out of hand, especially on Thaddius, is that they 'double dip' the damage multipliers. They're based off of fireballs that are critting in the neighborhood of 9K due to the Polarity bonus and everything else, and then they're also getting multiplied by an extra 10% for CoE, 15% from Improved Scorch, 10% from Firepower talents, and of course the 290% bonus from Polarity. And you're right, if your mages are seeing 20k+ ticks of Ignite early on in the fight you are not going to be able to keep them from getting stomped.

Personally, I use Arcane Missles for the first two shifts (I'm just as worried about compounding someone else's Ignite as I am about getting myself killed) and we do a lot of yelling on vent if someone's flying up the damage meter too fast. Our MT has also gotten really good at taunting him at just the right time our last couple of kills, which helps a ton.

No, that's not how Taunt works. It doesn't give the taunter threat equal to the person highest on the threat list, it gives the taunter threat equal to whoever the mob has targetted. Taunting Thaddius while he's already attacking you will do nothing but put the ability on cooldown -- the tooltip for Taunt even states that it has no effect if the mob is currently attacking you.

If the tank is quick and can taunt him right as he targets the mage with the runaway Ignite, though, he can give the rest of the raid quite a bit of breathing room.

But taunt doesnt work this way.
It does not grant the tank the highest threat anyone in the raid has at the moment the taunt occures. It boosts the threat of the tank to the level of the current aggroholder and makes the tank the current aggroholder.

Example:
Mage A has 125% threat of tank. But has no aggro since he is ranged and need to have 130% threat of the current aggroholder to switch.
Tank taunts. This taunt does NOTHING as the mage had higher threat but not the aggro.
Mage hast still 125% threat.
Next ignite ticks. Mage has 135%. Mage gets aggro. Taunt is on cooldown.
Mage down.

Preemptive taunting does nothing to prevent that.

The only way to have taunt help is to know who has the ignite and taunt when hes targeted on that mage and casting his~8k lightning bolt... hard to pull off since he targets someone every few seconds to CL them.

While having 1 mage hold the ignite for the longest time possible for the biggest dmg meter epeen, it doesnt help the raid (especially since that mage will be dead). The best way to do it from what we've found is simply spreading out the ignites to multiple mages. Not exactly an easy task, but you do what you can do... and everyone lives (well except thoses who run in the wrong direction but thats another part of the fight).

Its amazing how big of an aggro threshold a well geared Feral Druid holds in this fight. We can basically go all out on him with no fear of anyone pulling aggro.

Yeah, I wouldn't recommend having the MT taunt Thaddius when a mage pulls aggro with huge Ignites as an underlying strategy or anything. We do our best to not have mages pull at all. I just noticed that on our kill last week our MT saved mages twice with well-timed taunts.

I usually rank 1 scorch till about 90%, max rank scorch till about 75%, then fireball spam after that and it's not a problem. Non-TF warrior tank. If we're falling behind on DPS I toss fireblasts in the mix every other fireball, or if I think I can sustain it till the kill. It really shouldn't be too big a deal. If you see the #15 mage on SWStats jump up to #7, then #1, within 5 seconds, it's pretty obvious he needs to stop, and it should be called in mage chat, or vent, for all mages to stop. I've found that, under 70% or so though, it doesn't really matter how big the ignite gets, you're not gonna pull it from the tank. It's possible, just highly unlikely you can keep an ignite large enough and long enough to pass him.

In the first few transitions we use Arc Missiles, then unleash Fire during the last 5-10 seconds of the shift. That way Ignites don't roll out of control, UNLESS someone rolls them between the shifts (all it takes is one unattentive Mage).

After 60% or so, we usually try and roll it between shifts. At that point the dps is so insane its almost worth the death.

Last Thaddius didn't need Evo until 8% Just takes some practice and really communication between Mages.

Edit: oooh just got these forum ranks. Classic.
