*Edit at the bottom.
Most of us also got Heroic Glory of the Raider for a server second. Our Immortal run was a server third. Another guild beat us by a day. Anyway, Here is a pic of our new proto drakes. Unfortunately I forgot to turn Timerbuttons off.
Its funny how anti-climactic it is. The first kill of a tough boss is rarely clean so you have all the drama that the mistakes provide. With the Immortal its like your waiting for something that never happens. Its like having an awesome feeling because you got home from work safely.
Anyway, I'm very happy. Grats to everyone that got the achievement with me.
One other thing. I am really looking forward to running a stress free Naxx next week, assuming the patch doesn't drop.
Edit: I posted the above in haste last night just because I wanted to get it out there. Now that I've had a little more time to think there are a couple of other things i would like to say.
When I look around the forums and such there is quite a bit of debate on just how easy or hard The Immortal is and what it really measures. The way I look at it, The Immortal is deceptively hard, but should really be a fairly easy achievement.
In a way it's a lot like Archimonde in Mount Hyjal. Archimonde wasn't a hard fight. As long as you stay out fires, click your tiers, and decurse, it should go fine. However, one mistake by one person screws up everything. One death could cause three more, and those three would wipe the raid. Its relatively easy, but very unforgiving.
I would be willing to bet that a majority of "hardcore" raiders without the Immortal have killed every boss in naxx with out a death. They just haven't done it in a single week. We all know how to stay alive and keep our guildies alive, but a laps in focus here or there ruins it.
Some people claim that the Immortal is all about RNG. I agree that RNG can screw you, but it is unlikely that RNG will screw you week after week, and I think most of the times guilds miss it can be attributed in some fashion to player error. We had 3 really close weeks before we got it this week. I think our first near miss was RNG. We only had two tanks for adds on KT because we were doing the 20man achievement and both tanks were CCed. It might have been possible for a priest to get off a GS but that is pushing it a little bit. The next close call was lost due to player error, and our third miss was due to our collective ignorance of how the ice blocks worked on Sapphiron.
The trick is to learn from your misses. Unfortunately I don't think there is a big guide anywhere that says, this is your biggest issue on this boss, and that could happen on that boss. Little things that aren't a big issue normally come out and bite you. One of our early attempts at Immortal we lost because we chained a Holy Wrath during 4 Horsemen. We had killed 4 horsemen for several weeks without a death, but this week we chained it and someone died. It didn't happen again because we changed our strategy and we were more aware of the possibility.
Ultimately, I think this achievement has made me a better player, and is proof that I am a good player. The Immortal has forced me to pay more attention to my "oh shit" abilities, and shows that I am capable of avoiding damage. Now that is a skill to be proud of.
Thanks for all of the congratulations, and good luck to everyone still looking for the achievement.
