This is mostly towards Hyrion, but I'm posting it to the forum for general interest.
I was reviewing the upcoming WotLK changes to the Protection tree for warriors. Safeguard has the nice 20% damage reduction buff for the target of Intervene for 6 seconds. Which got me to thinking about the Azgalor fight. The zone-wide silence means that the MT is left for 5 seconds with only HoTs to replenish health until healers are able to cast again.
This fight is a survivability fight, not a dps race. Lets try positioning you to hit an Intervene on Heart at the start of each silence from his Howl of Azgalor. Stripping away one of his 8k hits should make the fight a lot easier.
Down the road when we have Safeguard available, this will be an even better way to push through periods of silence with less risk of a tank death.
