The fight has 2 phases. You must clear a corridor/gauntlet to pull Thorim into the main room to start P2.
In P1, split your raid in half. While the corridor group that should mostly consist of AoE heavy specs immediately enters the corridor on the left, the other half of the raid stays in the main room.
Be careful in the corridor/gauntlet, the last section is trapped, don't walk in the middle.
In P2, you fight Thorim himself and don't have to deal with adds anymore.
The Hard Mode for this boss is relatively easy, and is enabled by completing the corridor/gauntlet in less than 2:45 minutes.
Sif will be casting different abilities on the raid in P2, but it won't make a massive difference honestly.

Split your raid in half, with AoE heavy specs going in the corridor. Interrupt the Evokers and Acolytes. Do not run in the middle of the room leading up to Thorim at the end of the corridor.
