Everybody here is saying that you can just bubble and walk right in, or fly above the chandelier to escape them all. You all forget, however, that 3.3.5 is notorious for crashing in heavily populated areas, notably: Dalaran, Wyrmrest Temple, Stormwind, and...wait for it, the entrance to ICC. I've had it on numerous occasions where my client crashes just as I, a paladin, dismount above the chandelier. It's somewhat challenging to bubble when WoW isn't open anymore. Guess what that means? Corpse run! Everybody's favorite past-time activity! And yes, I've already used LAA to boost how much memory WoW uses. It mitigates the issue, not solve it.
Also, it's rather annoying how ICC rep farming turns into ICC rep AND repetitive corpse running every time RL has to reset. Brilliant.
I agree with OP, +1
