It's part of raid leading to be capable of observation or having his/her own raiders tell him/her what happened. If Venom Bolt Volley isn't interrupted more than once, that's bad. If the disease stacks to more than 4, that's bad.
One thing I can tell you that helped my guild a LOT was having disarms for the Drakkari Frozen Warlords and Jalak. Two Mortal Strikes at the same time could mean instadeath for your tank or close to it, and Jalak can easily 2-shot a tank after one or two Bestial Cry's. So you're very lucky that there's a Windwalker Monk there. Tell him to get Ring of Peace and work out a disarm and kill rotation for the Warlords and then repeat the disarm rotation for Jalak.
A Monk also has Grapple Weapon in addition to the Warriors having Disarm, the Rogue having Dismantle, and even the Hunter could get a pet that disarms. The Warlords are unable to do Mortal Strike while disarmed, and obviously disarming a boss like Jalak drastically cuts down damage.
Edit: I decided to take a harder look at the logs, specifically Damage Taken and what people died to. The most common trend I saw was tanks simply dying to Horridon's normal melee hits, BEFORE enrage. That is a real problem. Tank healing should be the least of your worries in that fight until the very end when it gets super insane. However, I can't be sure if this is a healer or tank problem. Also, a few times it even looked like tanks lost aggro on Horridon, which I don't even know how that can be possible, so I'll assume that's a bug in the log.
Second most common trend I saw was the disease stacking too high. People need to know they must NOT be hit by those undead. The Warriors can be CCed by anything, the Champions can only be CCed by stun. People need to run and/or stun. Assigning people, like melee, to kill/disarm Warlords while others, like ranged, kill Champions could be very useful here. I know that thins out DPS a lot, but this is why Bloodlust spells are used for this part. Use your Bloodlust spell when the first Warlord is at about 70%, and you should make it.
