Awaken

While doing my regular daily heroic routines with my characters, I got suprising request to come heal Valithiria Dreamwalker in Icecrown Citadel 25man.
Because of my 1 month Aion break I never had enough time to try 25man or even 10man in that wing, I was hesitating.
The asker told me I don't need to worry, there's no tactics I need to know.
Still he "forgot" to tell me they're killing Dreamwalker in heroic mode, and that I found out after the boss was dead, or in this case, very alive.
After that they wanted to continue Rotface and do it hardmode also. I was asked to join and we killed him in one shot.
I was so confused with all the tactics "be close boss, watch out slimes, run to other tank if you get debuff, be behind boss and watch out the slime spray". I managed to stay alive the whole fight and not mess up so badly (I hope!).
Since no one from their guild needed Helm of the Elder Moon I got it. How Lucky!

I also learned not to leave PoS after last boss when having "Jaina's Call"-debuff (atleast when flying outside instance!), since I left the group, was still stunned and fell to death.
