Strategy

Phase One

Take Cho'gall to a corner and have the ranged group up in the centre. When Cho'gall casts conversion you will need to stun, interrupt, disorient or CC the players affected and this will be much easier in a tight group. The tanks will need to switch off for Fury of Cho'gall.

When a Corrupting Adherent spawns all DPS must switch to it. You must be careful to interrupt Depravity and move out of the way of Corrupting Crash. If you gain corruption in this phase phase two will be much harder. Make certain the Corrupting Adherent dies in a corner and that the tank and melee run out as it is dying to avoid corruption from spilled blood of the old god. The add must die before Cho'gall casts Fester Blood. If you kill it in time you will then need to snare and AoE down the Congealed Blood of the Old God. Avoid being melee'd by these as they cause corruption.

Repeat the process with the next Corrupting Adherent and make certain it dies very close to the first Adherent. This time you will have twice as much blood of the old god. The third adherent will have thrice as much blood of the old god, acting as a soft enrage.

If you are close to phasing and have an adherent spawn continue damaging Cho'gall. The adherent will despawn at 25%.

Phase Two

This phase is relatively simple, you will take more damage from the AoE pulse depending on how much Corruption you gained in the first phase. If you hit 100 Corruption you cannot be healed and will die. You will still need to swap tanks for Fury of Cho'gall.

Cho'gall will spawn Darkened Creations in this phase. It is very important to interrupt and stun these so that they do not cast Debilitating Beam, which causes corruption and effectively removes a player from the fight. The first two or three waves should be killed, after that burn Cho'gall.

Heroic Mode

Two Corrupting Adherents will come at a time, causing double the normal amount of blood.

Shadow Lords and Fire Elementals will appear on Flame and Shadow's orders that must be damaged to reduce Cho'gall's stacks of their buff.

Spiked Tentacles that melee quite hard and have too much HP to kill will appear in phase two in addition to darkened creations.
