Last week Team Kaels made it up to Heroic Sha of Pride, but we were one person short on Friday (cough, SNUFF, cough) and as such, we were only able to get some 9-person practice runs in. We also got a few pulls in last night, and this evening we were able to kill him.
Regarding differences between Heroic and Normal, I have shamelessly stolen this from a guide at MMO Champions:
The first addition to the encounter on Heroic difficulty, is that the boss spawns Rifts of Corruption periodically, every 8 seconds. These Rifts spit out bolts at random raid members, which deal splash damage to anyone within the 5 yard AoE that pulses at the bolt's target [edit Tay: this also gives you 5 pride if you don't move out of it]. Rifts can be closed by any raid member walking over them, however doing so puts a debuff on that raid member which prevents them from closing any more rifts for 1 minute.. . .The second addition to the encounter on Heroic difficulty, is effectively a Pacman minigame - Banishment. A random player will be selected and Banished into the "Pacman" realm, at which point a Corrupted Fragment spawns at their location in the real realm which must be killed to bring the Banished player back from the "Pacman" realm. When Banished, players are constantly forced to be running forward, but can turn to survive the Pacman minigame to which they have been sent. There are Sha adds [edit Tay: GHOSTS!] which will one shot you if you run into them and clearly visible purple void areas to avoid. The aim of the game is to run around the maze, avoiding the adds (which move quite a bit faster than the player) and collecting the golden orbs present by running through them. Collecting a golden orb gives the Corrupted Fragment a 25% damage taken bonus, allowing it to be killed quicker. Once the Corrupted Fragment has been killed, the Banished player will be returned to join the rest of the raid and continue the encounter as normal.
