The Third Boss
Strategy
Like their contemporary Lucifron, Gehennas is flanked by two bodyguards that should be separated from the boss. There isn't anything too complex about defeating these mobs, however your tanks should use Free Action Potions to avoid being stunned by Fist of Ragnaros.
Once you've killed the boss' bodyguards, focus on Gehennas, who will use two main spells: Gehnnas' Curse, which should be removed from tanks as soon as possible, and Rain of Fire, which must be dodged by all members of the raid.

The Fourth Boss
Strategy
Garr is defended by a team of eight Earth Elementals. The more Warlocks you have in your raid, the easier this fight will be. In essence, each elemental can be Banished in turn, reducing the total overall damage inflicted on the raid.
Garr receives a passive buff after each Firesworn is defeated, gaining Enrage stacks which increased his attack speed by 10% each time. To limit damage, you should kill some of the elementals (between one and four) and Banish the others, or tank the remaining Firesworn while the rest of your raid focuses on killing the boss. In addition, each elemental explodes when it dies, inflicting damage to nearby players and launching them across the room
Finally Garr uses two abilities: Antimagic Pulse will remove one of your buffs during combat, and Magma Shackles slows all nearby players. Once you've killed the boss, all you have to do is mop up the remaining elementals.
