SHANNOX
Tank Shannox and Riplimb; swap every 30s. Dodge spears and traps. Hit Rageface with 40k after leap. Dps dogs to 5% and Shannox to 35% then kill dogs and nuke boss.

ALYSRAZOR
Kill talons, dodge blobs. Caster gets feathers and flies through rings.
Aggro hatchlings and feed them worms.
Boss summons dodgeable tornadoes, cuts flyer's wings then sleeps. Interrupt talons and nuke.
Boss wakes up, does massive aoe and frontal cone damage before she flies back up.

BETH'TILAC
Team 1 climbs up the web: dodge meteors, jump down during devastation.
Shoot spinners, tank drones, prio aoe spiderlings.
After 3 devastations, nuke and swap tanks every 20s.

RHYOLITH
Drive into volcanoes, runaway from stomp, dodge lava. Prio small adds, tank sparks away. At 25% nuke.

BALEROC
Queue for sparks, get out with 10 stacks of torment. OT takes over during decimation blade.

From my experience as guild and raid leader in Firelands content, killing both of Shannox's dogs is way easier, you only have to spam heal one tank in the end.

If interested, I can share my detailed guides I wrote for my guild for some of the bosses
nvm, I forgot that CWR is doing 10 mans, so my 25 man tactics are useless :/
