Realm First! Can't get any sweeter than that plus another server first title?
Last night we started with Patchwerk. We wiped about 3-4 times on him. Grobullus was 1 shot. Gluth took two attempts and so did Thaddius.
We took a break to gather all our frost resist gear, gem, and enchant them. Took 3 tries and he was down.
We headed to Kel'Thuzad's room and there he is ... waiting for us. Last time I saw him was 2 years ago with 39 other people. The planning took about 10 minutes making sure everyone knows where to go and what's their responsibilities.
We charged on! It was a long a battle really. In the end we ended up one shotting him.
