With the 3.3 patch, which appears to be coming VERY SOON. We are about to see some changes to achievements.
Brewmaster is going to remove most of the drinking and drunken stupidity. Valentines is going to have some changes, looks like maybe removing the headache of collecting the card, gift packs!
The largest impact to me will be the change to Proof of Demise becoming a Feat of Strength. ATM, I am only one of the dailies away from complete (Proof of Demise: Anub'arak).
Hopefully, I can complete this one tonight!! :) I was lucky enough to find a good group last night to complete the Occulus regular achievement and get Timear Forsees completed.
