The Fifth Boss
Strategy
One or two of your tanks should equip Fire Resistance gear before engaging the boss, as Baron Geddon inflicts heavy fire damage.
The Baron Geddon fight is not difficult itself, but an individual error may lead to a raid wipe. In particular, one of his spells must be reacted to above all else: Living Bomb. Geddon targets a random player with a debuff that cannot be dispelled, who must then distance themselves from the raid, as after 8 seconds that player will explode, dealing 3,200 points of damage in a 45 yard range. To avoid potential disaster, the Raid Leader should implement formations that keep Casters and Close Range DPS in separate groups.
In addition, melee classes will be subjected to Inferno, taking repeated damage for 8 seconds when within 45 yards of the boss. All melee classes should disengage the boss when he begins casting this ability. However, tanks with high fire resistance can survive this spell with healing focus.
Last, but not least, Baron Geddon will use a debuff that affects the entire raid. Ignite Mana rapidly burns the mana of a random target and must be removed from players in this order: Healers, then Casters. At 2% HP, Geddon will use his final attack, Armageddon, which must be either prevented, by killing the boss, or fled from, as Baron Geddon will explode after 5 seconds, dealing 8,500 damage to all targets in melee range.

The Sixth Boss
Strategy
Shazzrah is a boss that uses a multitude of different spells together to increase his damage output. To limit damage dealt to your players, your raid should be split into two near-identical groups. This boss should be tanked facing the rest of the raid, at the maximum distance possible to avoid unnecessary damage and to simplify heals on your tank.
Most notably, Shazzrah will debuff the majority of your players with Shazzrah's Curse, which increases damage taken by 100%. It's vital that this curse is dispelled before Shazzrah combos with Blink into Arcane Explosion, which deals massive damage to cursed players.
Finally, will cast Deaden Magic, a debuff that should be dispelled right away by appropriate classes. Players should also make sure they've stopped casting before Shazzrah uses Counterspell.
